Python Client doesn't check if tokens are valid or not

[blueelvis]

Hi,

Just started using the Python client. If wrong credentials are passed to the client and a query is made, the client returns a wrong exception as below -

  File "D:\dev\Code\influxdb.py", line 108, in query_from_influx
    return client.query_api().query_data_frame(query=query, org=organization_id)
  File "C:\Users\bluee\AppData\Roaming\Python\Python37\site-packages\influxdb_client\client\query_api.py", line 116, in query_data_frame
    _dataFrames = list(_parser.generator())
  File "C:\Users\bluee\AppData\Roaming\Python\Python37\site-packages\influxdb_client\client\flux_csv_parser.py", line 48, in generator
    yield from parser._parse_flux_response()
  File "C:\Users\bluee\AppData\Roaming\Python\Python37\site-packages\influxdb_client\client\flux_csv_parser.py", line 87, in _parse_flux_response
    raise FluxCsvParserException("Unable to parse CSV response. FluxTable definition was not found.")
influxdb_client.client.flux_csv_parser.FluxCsvParserException: Unable to parse CSV response. FluxTable definition was not found.

Instead, I believe that while creating the client, it should check whether it is able to connect with the specified credentials instead of trying to parse the response in the query down the line.

Hi @blueelvis,

Thanks for using client.

Could you please provide a more info?
Which version of InfluxDB do you use (cloud, beta, nightly)?

I prepared simple test case for that and the client correctly parse error response as Unauthorized exception.
