make_response_from_records returns None

[hieu-n]

Package version:

Python 3.6.1
Flask (0.12.2)
Flask-Excel (0.0.6)
pyexcel (0.5.1.1)
pyexcel-io (0.4.2)
pyexcel-ods (0.4.0)
pyexcel-webio (0.1.2)
pyexcel-xls (0.4.0)

In my code:

return make_response_from_records(records, file_type='xls', file_name=fn)

This raises an exception:

  File "/miniconda/envs/flecom/lib/python3.6/site-packages/flask/app.py", line 1725, in make_response
    raise ValueError('View function did not return a response')
ValueError: View function did not return a response

I stepped into make_response_from_records(...) and found this code which returns None:

# python3.6/site-packages/pyexcel_webio/__init__.py

def dummy_func(content, content_type=None, status=200, file_name=None):
    return None


__excel_response_func__ = dummy_func


def _make_response(content, file_type,
                   status=200, file_name=None):
    if hasattr(content, "read"):
        content = content.read()
    if file_name:
        if not file_name.endswith(file_type):
            file_name = "%s.%s" % (file_name, file_type)
    return __excel_response_func__(
        content,
        content_type=FILE_TYPE_MIME_TABLE[file_type],
        status=status, file_name=file_name)
