[NEXT-1190] TypeError: fetch failed in server componant since next 13.0.6 #44062
Comments

Same |
|
I no longer see the code that you attached. Are you fetching one of the API route with fetch within getSeverSideProps because that is not possible? |
|
Sorry, I solved it by removing the fetch from the layout and put it in the page. I used the new way to fetch data in a server component. But we should be able to fetch data in the layout. The problem came with the upgrade from Next 13.0.5 to 13.0.6 |
|
I get the same error in Next.js version 13.1.2. Still using the pages directory. Whether locally or on the server, the behaviour remains the same. No external fetch requests work and not even external images can be loaded with sharp. With Next.js version 12 everything worked fine. Has anyone found a workaround? |
|
I managed to solve this problem by using 127.0.0.1 instead of localhost in the fetch URL |
|
My current solution is to put the following at the beginning of next.config.js The reason is Node17/18 using ipv6 as default for localhost. node-fetch/node-fetch#1624 |
|
I'm getting this error on next:12.3.3 deployed on Vercel, |

For me this issue was caused by using self signed certificates for my development backend server. |

Not an issue for me with version 13.2.4, but using the latest canary of 13.2.5 broke it on local Windows machine using |
|
thanks buddy my issue solved |
can u tell us how please ? |
actually i had my backend api on So that time I found out this, that nextjs 13 fetch does not work for localhost api |
|
Error appears most likely on node 18, I downgraded version to 16 and issue got fixed |
|
I got the same errors and solved it. e.g. .env run then I tried modify it works fine. |
|
My solution to this was keep your dev server running while deploying it on vercel or ceating a local build... 💀 |
@Anas-Nabulsi You are my hero, this resolved |
|
I have similar error (ERR_INVALID_URL) with server-side fetch. Changing to 127.0.0.1 and other above-mentioned solutions don't work (haven't tried downgrading though). Calling external resources is blocked as well. I'm running Next v13.2.4 (dev mode) on Node v19.4.0 (Windows 10). |
It turned out that the URL was actually illegal. Sometimes invisible Unicode characters (like zero width non-joiner U+200C) can appear in unexpected places and it's kinda hard to hunt them down: https://invisible-characters.com/ |
|
I'm encountering the same error in a Docker environment.
I'm writing this for others as I couldn't find a similar workaround. # .env

Hi, since the original reproduction is no longer available, could someone who was experiencing this issue please confirm it is still an issue in the latest version of Next.js |
|
yes i still have this issue : Error occurred prerendering page "/questions". Read more: https://nextjs.org/docs/messages/prerender-error
the fetch url i use when my local server is running : |
|
@cyrine25 this is because you're trying to fetch from an internal api route during build, which is not supported. |
|
what do you mean? Can you give an example and how to fix?
|
|
I fixed the issue by using http://127.0.0.1:3000 and adding to every fetch request (cache: 'no-store',) |
|
@KoolP yes but that's good practice anyway - if you're fetching data from an external source it can fail at any time, so having a fallback makes sense @kirilkirkov if you add the |
|
I think that the best solution will be with - fallback data.. and immediately after build to remove the .next/cache/fetch-cache/* contents. |
|
@kirilkirkov check out this thread on the Fly.io forums where I've gotten some help figuring this out: https://community.fly.io/t/nextjs-build-vs-runtime-environment-variables/13760/9?u=jared1
The folks at Fly.io helped me figure out what's going on here; the difference between dynamic and static rendering of server-side components. The NextJS docs on the topic say that using Either the docs are wrong, or there's a bug somewhere. cc @timneutkens |
If the dynamic mode isn't automatically detected, you can also use https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config#dynamic to force it. |
|
got the same issue when fetch 'https://api.github.com/users/yiGmMk',in my case it's caused by api limit |
This was what I did and this works for me like a charm. |
Thank you! export const dynamic = 'force-dynamic'worked like charm. I wished nextjs could automatically detect the right behavior... doesn't feel like app directory is production ready for me |
|
Is there some PR or issue to investigate and fix this behavior? |
|
fyi in case you are facing issues due to |

Recently, I've updated my local setup and got the same issue. To fix |

I looked for this issue for quite a while with a Rails 7 backend and came to these conclusions:
Knowing that, I started to manually specify the Worth mentioning as well, I'm using a .env variable to define the Don't forget to add your .env variables in the var settings section of your website on your hosting platform (eg. Heroku). |

so in my In my scenario, I am using Django as the backend for my Next.js app. I make a request to /api/inventory/products in Next.js, which in it call fetch to Django's REST framework. To work around the "fetch failed" during build time, I followed these steps:
Please note that this is only a temporary workaround, but it has been effective for me. |

I am running into the same issue doing a fetch call export const getFetchUrl = (route: string) =>
`${
process.env.NODE_ENV === "production"
? process.env.VERCEL_URL!
: "http://127.0.0.1:3001"
}/${route}`;and my import { getFetchUrl } from "@/lib/getFetchUrl";
import { PageResult, SearchParams } from "@/typing";
import { redirect } from "next/navigation";
type Props = {
searchParams: SearchParams;
params: {
term: string;
};
};
async function SearchPage({ searchParams, params: { term } }: Props) {
if (!term) {
redirect("/");
}
{
/**Fetch from API... */
}
const response = await fetch(getFetchUrl("api/search"), {
method: "POST",
body: JSON.stringify({ searchTerm: term, ...searchParams }),
});
const results = await (response.json()) as PageResult[];
console.log(results);
return <div>{/**Result list */}</div>;
}
export default SearchPage; |
|
I was able to fix this by wrapping the fetch in a try/catch, like so: |
|
I tried the below and getting status OK on the network but no data is being returned async function SearchPage({ searchParams, params: { term } }: Props) {
if (!term) {
redirect("/");
}
try {
const response = await fetch(getFetchUrl("api/search"), {
method: "POST",
body: JSON.stringify({ searchTerm: term, ...searchParams }),
});
if (!response.ok) {
// Handle non-successful responses (e.g., 404, 500, etc.)
throw new Error("API Error: " + response.status);
}
const results = await response.json();
console.log(results);
return <div>{/** Result list */}</div>;
} catch (error) {
// Handle fetch-related errors
console.error("Fetch Error:", error);
return <div>Error fetching data. Please try again later.</div>;
}
} |
well yeah, I tried the same thing, doesn't break but no data is returned so nothing is rendered in the Page where I'm using that data |
|
I also getting this error on next@13.4.12 everything works fine on locally but getting this error on deployment in vercel. changed Want to see my code details https://github.com/Sumitmaithani/competency-passbook |
Wait what?? Why would u use localhost in production after deploying?? |
I kept getting the above in Vercel logs and would also see the following error in my app:
These are the steps that worked for me:
|
Same thing on my end. No error but no data is returned and nothing is rendered in the Page. And the network tab when inspecting the page shows status ok |
|
running the is there a proper way to get rid of the error? |
I used |

Hey all, as alluded to in Tim’s comment, attempting to fetch from internal API routes at build time is not supported. The recommended way to handle this would be to perform the actual underlying server calls (ie, directly querying a database) in the component rather than attempting to fetch it externally. This will also have improved performance, since you’ll be able to avoid an extra roundtrip for when your fetch calls back to your server. See the “fetching data on the server” section of the data fetching docs for some information about this. There’s also this excellent response from a community member in our discussions forum. As noted earlier, there’s no local API server running when you trigger a build, so there’s no underlying API to fetch, thus causing the fetch request to fail. The same is true when deploying your application: your API server will most likely not be running on I’ll be closing this thread as it’s by design, but please feel free to continue the conversation over in the discussions forum! |
