Using Api crashes CLI; Port 7071 already in use #609
Comments
ANOTHER related scenario / repro case(providing a code repository...) Following along with Code 5-12 from the book Beginning Azure Static Web Apps and using the repository for chapter 5 here... Navigating to http://localhost:4280/ causes the CLI to crash/stop. Microsoft Windows [Version 10.0.22621.819] C:\Users\User Name>cd C:\MyRepos\Code\Samples\beginning-azure-static-web-apps\chapter-5 C:\MyRepos\Code\Samples\beginning-azure-static-web-apps\chapter-5>swa start https://localhost:5000 Welcome to Azure Static Web Apps CLI (1.0.3)

Hi @scafaria , can you please try starting SWACLI using the command |
|
I've moved to other workflows these last few weeks, but I want to help you diagnose so I'm trying to remember how to get back into this... I ran from a command line: npm install -g @azure/static-web-apps-cli And it said: And then I ran: And to my surprise it says And of course swa start http://localhost:5000/ doesn't work for me either right now. Sorry I can't be more helpful. |
|
Please feel free to track the original issue #663 |
|
@scafaria Thank you very much for your feedback. If you still care about this issue, please try the following steps:
The reason is that you are using a dev server (Blazor) with api, so just set api-devserver-url instead of api-location (which will use azure-function-core-tools to start api again, leading to "port 7071 already in use"). Hope that can help. |
|
Close the issue. Please feel free to open it if the error occurs. |
ISSUE:
Error Port 7071 is already in use. Switching to 7072 doesn't help either. Using the Api crashes CLI.
USING:
Node v16.18.1, swa v1.0.3, Windows 11, Visual Studio 2022, Blazor, Core Tools v4.0.4895, Function Runtime Version: 4.13.0.19486
SETUP
Add new Blazor Client and Api projects to solution. Set both as startup projects.
Api launchSettings.json of:
{
"profiles": {
"Api": {
"commandName": "Project",
"commandLineArgs": "--cors * --port 7071",
"launchBrowser": false
}
}
}

"iisSettings": { accepted defaults },

NOW
I see in the swa start console window:

I see the Client swa launches successfully at https://localhost:5000/.

in the func.exe window I see:

NEXT
Despite seeing the error about port 7071 in use, I forge ahead and try hitting the Api endpoint using port 4280.
http://localhost:7071/api/Function1
This works ONCE and then crashes CLI.
The console reads:
