it works with v2.26 but does not work for the v2.27

Hey @Oluwasetemi Ojo, that's interesting. I'm wondering what happens if you add

retryWrites=false

as a query parameter to your MongoDB connection string. If adding that query param doesn't work, do you mind creating a github issue to help us reproduce track this issue?

I tried adding it but it still would not work. I will try to create the Github issue.

Thanks @Oluwasetemi Ojo!

That's the error for not having a replicaset running.

can you explain better @dpetrick?

You need to initialize a replicaset for your mongo deployment, this issue tracks it on our side: https://github.com/prisma/prisma/issues/8266 Theres a link to a guide to set up a single replica set in the issue.

okay.
