    Error: Cannot use GraphQLScalarType "BigDecimal" 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.

Something went wrong
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

Steps to Reproduce

1. yarn
2. yarn prestart

Expected Behavior GraphQL Code Generator should complete successfully.

Additional Context even adding graphql resolutions won't fix this in yarn.

There are no bootstrap docs in the readme. its more like an about page.
