1032694511 I_kwDOAMm_X849jarv 5882 Opening remote file with OpenDAP protocol returns "_FillValue type mismatch" error 42075938 closed 0     9 2021-10-21T16:27:17Z 2021-10-29T09:30:40Z 2021-10-29T09:30:40Z NONE      

What happened: When trying to open a remote file with OpenDAP protocol, I receive the error Not a valid data type or _FillValue type mismatch: b'http://opendap.tudelft.nl/thredds/dodsC/IDRA/2019/10/01/IDRA_2019-10-01_11-00_raw_data.nc'.

What you expected to happen: I expect the file to be opened without having to add the string '#fillmismatch' to the file's URL (see example below). I am not specifying any engine in the method open_dataset(). However, if I specify 'pydap', I receive a different type of error: unrecognized engine pydap must be one of: ['netcdf4', 'scipy', 'store']; although I have pydap 3.2.2 installed and ran !pip install xarray[complete]

Minimal Complete Verifiable Example:

python url = 'http://opendap.tudelft.nl/thredds/dodsC/IDRA/2019/10/01/IDRA_2019-10-01_11-00_raw_data.nc' ds = xr.open_dataset(url+'#fillmismatch')

Anything else we need to know?: Unidata/netcdf4-python#929

Environment: - Ubuntu 20.04 - JupyerLab running on Docker.
