On attempting the ifft, the process died with an error of:
_Error executing process > 'frb:bform_frb:ifft (1)'
Caused by:

On inspection of the workd directory, it turned out the y polarisation file was missing:

The suggested solution is to investigate the polarisation calibrator. You may need to run with --nopolcal in order to force polcal solutions to an empty file that does exist, and proceed past the ifft step.
