const schemaData = parsed.data
      ? parsed.data.__schema
      : parsed.__schema
        ? parsed.__schema
        : parsed;

    return schemaData;
  }

  if (ext === ".graphql" || ext === ".graphqls" || ext === ".gql") {
    return await buildIntrospectionSchemaFromSDL(new Source(result, file));
  }

  if (ext === ".ts" || ext === ".tsx" || ext === ".js" || ext === ".jsx") {
