The JSON Schema Discovery fails to generate a JSON schema when applied to a collection containing JSON documents of the same structure and attribute order.

This issue arises because the output of collectionToWork.count() does not meet expectations, resulting in no return value from the aggregate function in RawSchemaUnorderedResultController.

Possible solutions:

1. The whole process can be done within the collectionToWork.count().then((data) => {...}
2. or async/await can be used.
