Using a prismaObjectType results in a union type that is too intricate to illustrate

I am currently working on a node project in TypeScript using graphQl and prisma-nexus.

When utilizing the prismaObjectType from 

import { prismaObjectType } from 'nexus-prisma'
, I encounter a complex union type that cannot be represented easily.

While I can still run the project in development mode, attempting to build it with tsc -p results in the following error: 

error TS2590: Expression produces a union type that is too complex to represent.

Has anyone else faced this issue before? Any suggestions on how to resolve it or potentially ignore it during the build process would be greatly appreciated.

Thank you in advance for your help!

Answer №1

The fix was shared in a thread regarding the nexus-schema-plugin-prisma on GitHub.

Whenever utilizing prismaExtendType, remember to include a string of the object type as a type parameter. For instance, if you are dealing with a prisma model type named "User," make this adjustment:

prismaObjectType({/*config object*/})

to:

prismaObjectType<"User">({/*config object*/})

Answer №2

Expanding further on my previous comment:

A GitHub issue has been raised regarding this concern, which recommends downgrading Typescript to version 3.4.X.

Prisma 1 is currently undergoing a transition period in favor of the newer version, Prisma v2 / Photon. While maintenance for Prisma 1 will continue, most focus seems to be shifting towards Prisma 2:

Although Prisma 1 will still receive maintenance, the majority of Prisma's development efforts are being directed towards Prisma 2

No new features are planned for Prisma 1.

While I do hope that this issue gets resolved, it seems like upgrading to Photon and transitioning away from Prisma 1 may be the recommended solution.
