gatsny build fails at: Building static HTML for pages failed with

[zilahir]

Description

I have been struggling with this for weeks now.

gatsby develop works as expected, all the data getting processed, all the pages rendered correctly, but gatsby build fails with the following issue:

error Building static HTML for pages failed

SyntaxError: Unexpected end of JSON input

  - JSON.parse

Steps to reproduce

get any api endpoint which returns json like as string, then use:

let demo = JSON.parse(sometJson),

then try to map it through:

demo.map((e, i) => (

In dev, works like charm, as it should. The issues occurs when i am trying to build.

Expected result

Not throwing unexpected end of json input

Actual result

See image attachment.

hello @zilahir could you provide a minimal reproduction of the issue, maybe a github repo?

[zilahir]

hello @gurpreet-hanjra , thank for your reply. well i can give u a github repo, but then i'd need to provide you my API credentials, since you won't be able to test it without those. I will figure out something soonish!

Thank you!

[gurpreet-hanjra]

Great, thank you.

@zilahir you could also mock the API with a JSON file as I'm pretty sure it's not really Gatsby related but more on the data part of it. So if you could reproduce it with maybe something like below that would be enough :)

const demo = JSON.parse(`your response`);

return demo.map((e, i) => (`
