To Reproduce

Switch config of src/pages/api/replay to:

export const config = {
  runtime: "edge",
};

And execute npm run dev.

(apologies, the repo isn't technically a minimal reproduction (as 13.0.7, seems to break in other ways), but the issue / solution should be clear. If not I'll create one a minimal reproduction).

Describe the Bug

Next.js supports putting pages in the src directory.

So when I tried testing GA version of edge functions (#44045 cc @feugy), I received the following error:

Page /src/pages/api/replay provided runtime 'edge', the edge runtime for rendering is currently experimental. Use runtime 'experimental-edge' instead.

I see that #44045 looks if the route starts with /pages so a /src/pages route throws it off. The solution seems like it should look in the src directory too.

A temporary workaround is to move the pages outside of the src directory.

Expected Behavior

If src directory is supported then edge API routes hosted in src/pages/api shouldn't error.

Which browser are you using? (if relevant)

Here’s a minimal reproduction: https://github.com/controversial/nextjs-edge-functions-ga-error-repro

In the commit history, you can see that the penultimate commit (git checkout HEAD~1) works, while the most recent commit (which just moves pages → src/pages; git checkout main) fails.

Note that this error still exists in the 13.1 release, as well as in the 13.1.1-canary.0.

The 13.1 release notes advertise that

"experimental-" prefix is no longer needed

but this isn’t true if a project uses a src folder.

Hi, this has been updated in v13.1.4-canary.1 of Next.js, please update and give it a try!

[feugy]

Thanks for the bug report @controversial, and apologies for the lag. Let us know if you have other related blockers!

[controversial]

Thanks for getting on this @feugy! The main other related (as far as edge API routes) blocker for me is #38302
