Fix InternalServerError

✅ Solution

The "InternalServerError" in graphql-yoga often arises from prematurely closing a readable stream, especially with serverless environments or when integrating with frameworks like Fastify. Ensure that any stream processing logic within your resolvers or middleware correctly handles stream completion and avoids calling `stream.end()` before all data is pushed. Verify that the graphql-yoga response is allowed completion before disposing of any dependent resources.
