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

[joncursi]

After upgrading from apollo@2.12.2 --> apollo@2.12.3, I started receiving the following error while trying to download my schema:

> apollo service:download --endpoint=$API_ENDPOINT_PROXY/v2/graphql graphql-schema.json

  ✔ Loading Apollo Project
  ✖ Saving schema to graphql-schema.json
    → spurious results.
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.

Downgrading back to 2.12.2 causes the error to go away.

[mikea]

This seems to be caused by changing required dependency in apollo package from "^14.2.1" to "~14.2.1"

Which is caused by: #1291

Even tough I've downgraded it does not fix anything for me :/

If this complete list could signifie somethinkg to you ?

If you are using npm:

• Copy the version of graphql from your node_modules/apollo/package.json
  • For me at the time of writing it's "graphql": "~14.2.1
• Paste that in your project's package.json to make sure it matches exactly what apollo is using
• Run rm -rf node_modules/
• Run npm i
• Run npm dedupe

[githubflub]

I changed my backend's folder structure around and started getting this error while using serverless-offline and refreshing the local version of my UI. The fix for me was to change this line in my webpack config

externals: [ nodeExternals() ],

to

externals: [ nodeExternals({ modulesDir: path.resolve(__dirname, 'node_modules') }) ],

This fix probably doesn't apply to you if you are using a standard folder structure. I don't even know why this worked.

@flippidippi dedupe can't work if we are in a monorepo submodule whith a local import as those imports will not have anything left in there node modules

In case anyone has a variable version like this 14.0.2 - 14.2.0 || ^14.3.1,:

1. Pick one and put it in both your packadge.json and in node_modules/apollo/packadge.json
2. Delete node_modules/apollo/node_modules
3. CD into node_modules/apollo/
4. Install deps in node_modules/apollo/
5. Install deps in your project

@Sceat did you made it work for you in monorepo ?

[Sceat]

@Sceat did you made it work for you in monorepo ?

Nop it's not possible, neither to link other project using Graphql.js this realm security is imo useless and makes things overcomplex, i resolved it by refactoring my whole monorepo to import 'graphql' in only one place. Note that this security also prevent us from using a commonjs library that use graphql & using it ourselve through esm, that said i also moved away from all that heavy apollo stuff which has enough line of code to sink the earth into a black hole 😁 good luck my friend, i opted to write my own graphql solution on top of the graphqljs lib

[hamzahsn]

have you tried to use resolutions in package.json ?

[Sceat]

Yup, and all sort of others things like burning sand in a cup shouting chinese words but no success..

[hamzahsn]

@Sceat well, it works for me now with apollo schema:download but I have a small issue with apollo codegen:generate, anyway, I have made resolutions in top package.json file and that did the fix
