• Summary

This package's package.json defines a forced resolution of graphql to ^15.4.0. Graphql 15.5 was just released, and this is causing a problem with yarn's resolution:

    Error: Cannot use GraphQLScalarType "String" 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 think that forcing a resolution in package.json in my project would work, but there is no reason for this package to also force the resolution internally.
