mesh build fails with "Cannot find module" for the successfully generated introspectionSchema

[danbim]

Hi! I'm stuck here. mesh dev works just fine. If I run mesh build though on this .meshrc.yml

sources:
  - name: mysource
    handler:
      graphql:
        endpoint: http://localhost:8000/graphql
        operationHeaders:
          X-User-ID: "{context.headers['x-user-id']}"
          X-User-Email: "{context.headers['x-user-email']}"

the process fails with the following error:

💥 🕸️  Mesh - mysource Failed to generate the schema Error: Failed to fetch introspection from http://localhost:8000/graphql: Error [ERR_MODULE_NOT_FOUND]: Cannot find module '[...].mesh/sources/mysource/introspectionSchema' imported from [...]/node_modules/@graphql-mesh/utils/index.js
Did you mean to import [...]/.mesh/sources/mysource/introspectionSchema.ts?

Any ideas?
