jina.excepts.BadClient: StatusCode.UNKNOWN error in grpc: Exception iterating requests! often the case is that you define/send a bad input iterator to jina, please double check your input iterator

[alexcg1]

Problem

• Cookiecutter ran okay
• pip install -r requirements.txt okay
• python app.py index led to:

Traceback (most recent call last):
  File "app.py", line 54, in <module>

    f.index_lines(filepath=data_path, batch_size=16, read_mode='r', size=num_docs)

[JoanFM]

This error means that no input has been provided, so check the input iterator or generator provided in the input

[rutujasurve94]

This has been fixed and both indexing and querying work fine.
