Multiple instances of "graphql"

[jnak]

On a fresh install, I get this error when running yarn dev:

yarn dev
yarn run v1.10.1
$ npm-run-all --parallel start playground
$ nodemon -e ts,graphql -x ts-node --no-cache -r dotenv/config src/index.ts

Error: Cannot use GraphQLSchema "[object GraphQLSchema]" 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.

https://yarnpkg.com/en/docs/selective-version-resolutions

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.

I suspect this is because renovate-bot automatically upgrades dependencies and there are no tests setup in this repo.

FYI I reverted to https://github.com/prisma/graphql-prisma-typescript/commit/2d4994cec0b5c0b4f3c5ff1d0372dd0e1cea166f and it seems to work fine. I had to use npm install thought because yarn was failing:

error An unexpected error occurred: "https://registry.yarnpkg.com/flatmap-stream/-/flatmap-stream-0.1.2.tgz: Request failed \"404 Not Found\"".
