Error: no optional dependency [mongodb] defined in peerOptionalDependencies in any package.json

[matiastucci]

Describe the bug

I keep getting Error: no optional dependency [mongodb] defined in peerOptionalDependencies in any package.json. It's so weird because I see it most of the time but no always. Sometimes I can sign in correctly and sometimes I get redirected to /api/auth/signin?error=Callback# and see this error in the client: Try signing with a different account. This is the full error log:

To Reproduce
My code is in a private repo but if it's necessary I can try to create a new project and replicate it. My code is pretty standard. Just followed the docs. I only have 1 provider (Google) and I've already tried emptying the 3 collections (accounts, users and sessions)

Documentation feedback
Documentation refers to searching through online documentation, code comments and issue history. The example project refers to next-auth-example.

• Found the documentation helpful
• Found documentation but was incomplete
• Could not find relevant documentation
• Found the example project helpful
• Did not find the example project helpful

Hi there! Hmm that's odd. It would be appreciate if you could share a link to a repo to replicate this issue.

I wonder if it's related to a custom webpack or babel config that is maybe doing something odd (or possibly a typo in an import statement somewhere?)

[matiastucci]

thanks for answering. Can I add you to the repo?

EDIT: at the time posting the link I tried it and asked a friend to try it too and we both were seeing the error. I just tried it again and don't see it 🤔

I have the same issue:

I'm also experiencing the same issue:

FYI, I didn't see this issue for 2 days and now I'm seeing it again. Didn't change any back end code though. But I noticed that 1 minute before seeing this error I got this one:

not sure if it's related

Getting a new error now 😢 Still not touching any back end code. Same error in the logs (Error: no optional dependency [mongodb] defined in peerOptionalDependencies in any package.json)

[nyedidikeke]

Please share link to public repository or steps to replicate including versions (Nodejs, npm, etc.).

[IRediTOTO]

I have this error too

[IRediTOTO]

Getting a new error now 😢 Still not touching any back end code. Same error in the logs (Error: no optional dependency [mongodb] defined in peerOptionalDependencies in any package.json)

I got this, let's see in the Warning https://next-auth.js.org/providers/google

[IRediTOTO]

I think I fixed it, just need delete package.lock and node modules then run npm i again

[iaincollins]

I cannot replicate this with the example project and am not seeing this issue on other projects.

If you are experiencing a problem please provide an example with steps to replicate.
