I was running bilby_pipe on a .gwf file containing a GWpy TimeSeries. When bilby reached the resampling it defaulted to lal and produced the following error:

17:03 bilby_pipe INFO    : Resampling data to sampling_frequency 4096.0 using lal
XLAL Error - XLALResampleREAL8TimeSeries (ResampleTimeSeries.c:188): Invalid argument

I assume this is because XLALResampleREAL8TimeSeries couldn't recognise the GWpy timeseries. I think it would make sense if bilby were able to recognise the type of timeseries it is trying to convert and then to select its resampling method autonomously. Alternatively, could this error message recommend changing the resampling method in the config file?
