Problem

Setting up a new server using advanced TS example (via prisma cli) throws the following error:

Error: Cannot use GraphQLSchema "[object Object]" from another module or realm.

Ensure that there is only one instance of "graphql" in the node_modules
directory. If different versions of "graphql" are the dependencies of other
relied on modules, use "resolutions" to ensure only one version is installed.

Duplicate "graphql" modules cannot be used at the same time since different
versions may have different capabilities and behavior. The data from one
version used in the function from another could produce confusing and
spurious results.

Workaround

As per the following suggestion, adding a resolutions key to the package.json of the newly initialized project fixes the issue:

"resolutions": {
    "graphql": "^0.13.0"
  }

graphql-boilerplates / typescript-graphql-server

Ensure that there is only one instance of "graphql" in the node_modules directory
