set_probegroup fails when recording NWB file has sampling rate attribute instead of timestamps

set_probegroup fails when recording NWB file has sampling rate attribute instead of timestamps, e.g.

recording = se.NwbRecordingExtractor(file_path=data_path, electrical_series_path='acquisition/TimeSeries_32000_Hz', \
                                     load_time_vector=True, use_pynwb=True, \
                                     cache=True, stream_cache_path=cache_path)
recording = recording.set_probegroup(probegroup)

It works fine when timestamps are explicitly specified when the recording NWB file is generated.

This is a shortcoming that should be fixed as NWB files can have either specification.

Can you copy the issue to Spikeinterface and paste the error as well? Thanks!

Done. Thanks
