I get the following error when I run the server:

https://github.com/graphql-nexus/nexus-plugin-prisma/pull/913 may fix this issue?

I've performed a clean install but the issue persists.

I encountered this issue when using one of the prisma graphql examples (https://github.com/prisma/prisma-examples/tree/latest/typescript/graphql). It worked for me after updating dependencies to the newest packages.

OLD
"@nexus/schema": "0.16.0",
"@prisma/client": "^2.8.1",
"nexus-plugin-prisma": "^0.21.0"

NEW
"@nexus/schema": "^0.17.0",
"@prisma/client": "^2.10.0",
"nexus-plugin-prisma": "^0.23.0"

@MitchellMonaghan Thanks! Updating dependencies to the latest seems to fix it.

Was having the same issue, with the same dep versions as @MitchellMonaghan. Upgrade also cleared it up :+1:

I'm having the same issue:
"@nexus/schema": "^0.18.0",
"@prisma/client": "^2.12.0",
"nexus-plugin-prisma": "^0.24.0",

There has to be a bug somewhere in this library.
