DBAuth - Can't authenticate on Vercel

[jacebenson]

I was able to get close but still not getting success.

Here's the issue. If you make a repo, build a homepage, setup db auth, add a layout w/login/signup/logout links it works locally, but doesn't work on vercel.

Issue 1: Vercel base64's the body if there is one. This isnt handled currently. I think that code to handle this should be in here: https://github.com/redwoodjs/redwood/blob/0e49b9d86cc996d5ffe548d081887d4feed5675e/packages/api/src/functions/dbAuth/DbAuthHandler.ts#L423-L438 but... that's my guess.

Issue 2: Even when I parsed the base64'd data in auth.js, I kept getting a http response of 502 with the following message;

An error occurred with this application.

BODY_NOT_A_STRING_FROM_FUNCTION

Maybe correcting that in the typescript file will correct this, but I wasn't able to get around it.

Here's a link to the repo I was trying ot get this to work on.
it works locally but not on vercel.

@jacebenson I’m not 100% sure you can modify the event body as here:

https://github.com/jacebenson/rw36dbauth/blob/37276e094f69d679319d73a4f5df4f0ab8084257/api/src/functions/auth.js#L11

instead could you try the decode the body into a new variable and use that instead of referencing event.body in the remaining code?

[jacebenson]

Yea, Trying that seems to do the same thing. I updated the repo with the new attempt.

On login im getting

An error occurred with this application.

BODY_NOT_A_STRING_FROM_FUNCTION

Actually, I didn't look closely at the function, but I don't think you can do this here -- or make a copy of the event.

It will need to be done in DbAuthHandler instead probably around here:

https://github.com/redwoodjs/redwood/blob/0e49b9d86cc996d5ffe548d081887d4feed5675e/packages/api/src/functions/dbAuth/DbAuthHandler.ts#L207

This issue was filed on the wrong repo. But @cannikin and danny fixed this here I think.
redwoodjs/redwood#3309

It should be in the next release.
