The IOC fails to start with the following error message:

PandABlocks-ioc/src/pandablocks_ioc/_tables.py

Line 387 in 35360f4

initial_value=field_details.labels.index(initial_value),

Below is the traceback. I inserted some helpful print statements in the code, so the line numbers in _table.py are shifted by 3.

field_details=TableFieldDetails(subtype='enum', bit_low=16, bit_high=19, description='The trigger condition to start the phases ', labels=['Immediate', 'BITA=0', 'BITA=1', 'BITB=0', 'BITB=1', 'BITC=0', 'BITC=1', 'POSA>=POSITION', 'POSA<=POSITION', 'POSB>=POSITION', 'POSB<=POSITION', 'POSC>=POSITION', 'POSC<=POSITION'])
field_details.labels = ['Immediate', 'BITA=0', 'BITA=1', 'BITB=0', 'BITB=1', 'BITC=0', 'BITC=1', 'POSA>=POSITION', 'POSA<=POSITION', 'POSB>=POSITION', 'POSB<=POSITION', 'POSC>=POSITION', 'POSC<=POSITION']
type(labels) = <class 'list'>

The error happens while processing SEQ2 module, which has an empty table. The exception is raised for TRIGGER column of the table.
