Error encountered with "ct: true" while using the 1.0.4 singularity.

[BohBio]

Update:
While I could run the singularity program, once I add "ct: true", following are the error messages I receive:
invalid field ct, expected one of: 'alpha', 'beta', 'dp', 'edge_mutation', 'edit_fraction',
'fwd_is_reverse', 'input_bam', 'junction_overhang', 'keep_all_edited', 'known_snp', 'min_variant_coverage', 'non_ag',
'reference', 'rev_is_reverse', 'reverse_stranded_library', 'single_end', 'skip_duplicate_removal'

Please do let me know how to incorporate the ct flag.

(can ignore: "I have tried using the cwl based method to run the example data, but I ran into quite a bit of errors (possibly owing to conflicts arising from Python 2.7 and 3.8, I think). Thus, I would much appreciate if there can be an explanation for using Sailor (1.2.0 ?) using bash.")

Thanks!
