Weird 404 on my api routes

[fabien-h]

In dev everything works.

Once deployed, everything work...ish.

• The api returns the right result and status code when called with a curl.

- In the logs in my Vercel dashboard, I see a 200:

- In the browser, I get the right result:

- But in the browser, I get a 404:

Any one knows where this 404 comes from ?

This method is just a healthcheck. Here is the code:

return serverResponse.status(200).send('OK');

Since I get the OK, it means that the method works. I get more complex response for other routes. Evrything seems to work. Except that I get this 404 response code everywhere for no obvious reason.

Ok, here was the issue. I had a /api folder at the root of my project. This folder was used for the imports in my /pages/api. I noticed something weird in the compiled output for my deployment. A /api folder with all the functions inside. They were callable with a curl, but returned a 502, which seemed pretty normal.

Conclusion : don't have a /api folder at the root of your project, it will mess up the deployment. Even if it works locally.
