MissingSchemaError | Nextjs + Mongoose

[Jossdz]

Hi!

I'm deploying my application on Vercel and works well the first time I connect, after a few minutes it throws this error:

This is how I'm connecting to db

And here you have and example of my Models:

This is my really, really wild guess and I may not be making much sense. The default export of mongoose package is an instance of Mongoose (See here).

In serverful scenario, since every places import from the same package, they will all receive the same instance. You call Mongoose.models in one file and the mongoose in the other files will acknowledge that because they are all the same instance. This is not the case with serverless where every file/function is independent from each other so each might not have imported the same Mongoose instance.

Again, a really wild guess that may not make sense.

This is kinda the same thing that Passport does.
