Prisma MongoDB - Connection timeout problem.

Bug description

Hi, I’m using Prisma with MongoDB Atlas. I deployed my project with Heroku and if someone didn’t visit my website for a while. My prisma apollo queries causes a problem because of prisma mongodb query inside of it.

For example: I visited the website and I saw error, I refresh the page and then error gone. After a few hours I revisited the website again I saw error after refresh the page the error gone.

My connection url:

DATABASE_URL=“mongodb+srv://<user>:<pass>@serverlessinstance0.mongodb.net/<dbName>”

How to reproduce

Expected behavior

Connection shouldn’t be closed even though no one request any query. At least they shouldn’t see a error page.

The query you are trying to execute probably just takes longer than these 10s (including the creation of the database connection). I suggest you open a new discussion in this repository so we can discuss this and ask all teh questions - in an existing and closed issue that is not really appropriate as it notifies all the previous participants of the discussion on each comment.

hey @casperibo, I also experience this issue while using Prisma 3 (3.15.2 precisely), also using MongoDB Atlas

I just upgraded it to the latest version (4.3.1), which seems to resolve the issue 🤞
