Cannot compile example

[fdietze]

I'm trying to run the example like this:

sbt example/fastOptJS::startWebpackDevServer

And then I get the following error:

→ Cannot use GraphQLObjectType "Query" 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.

What I already tried:

• useYarn := true
• check node_modules folders (project and global) and lock-files for other graphql dependencies
• upgrading apollo dependencies apollo and @apollo/client
• npmResolutions in Compile := Map("graphql" -> "14.7.0") in build.sbt

all versions look fine (with npmResultions):
