GraphQL Error #7818

Open behnik opened 2 years ago

behnik commented 2 years ago

Error: Cannot use GraphQLObjectType "RoleConnection" 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. at instanceOf (/app/node_modules/parse-server/node_modules/graphql/jsutils/instanceOf.js:35:13) at isObjectType (/app/node_modules/parse-server/node_modules/graphql/type/definition.js:122:34) at isType (/app/node_modules/parse-server/node_modules/graphql/type/definition.js:92:32) at isNullableType (/app/node_modules/parse-server/node_modules/graphql/type/definition.js:422:10) at assertNullableType (/app/node_modules/parse-server/node_modules/graphql/type/definition.js:426:8) at new GraphQLNonNull (/app/node_modules/parse-server/node_modules/graphql/type/definition.js:379:19) at Object.load (/app/node_modules/parse-server/lib/GraphQL/loaders/parseClassQueries.js:109:13) at /app/node_modules/parse-server/lib/GraphQL/ParseGraphQLSchema.js:109:25 at Array.forEach () at ParseGraphQLSchema.load (/app/node_modules/parse-server/lib/GraphQL/ParseGraphQLSchema.js:107:71)

@behnik it seems that you have 2 graphql versions into your project. If you do not have installed graphql, you can use Yarn resolutions to force all your packages to use the same graphql version: https://classic.yarnpkg.com/lang/en/docs/selective-version-resolutions/

I experienced the same error after upgrading Parse Server and Parse Dashboard to the latest version. It seems that each required their own GraphQL version.

I had no specific version constraints so I removed the package lock file, removed the dependencies from package.json and then added them back one by one. First I installed Parse Server and Parse Dashboard afterwards. This worked for parse-server v. 5.2.0 and parse-dashboard v. 4.1.0.
