Additionally, in using the automatic import from BIDS/.json files the short and long echo times are incorrect - for my fieldmaps they are 4.12 ms and 6.58 ms respectively (with the auto import they are set at 10 and 12.46) - maybe because the units are assumed to be Hz (for some reason the units were not found in the files) but in the .json files they are in ms. The total EPI readout is set correctly.

When I specify the fieldmap type manually and leave the "read double-echo timing from BIDS / .json files" I receive a different error (see below). However when I manually define everything it runs fine.

Not sure if these issues are a result of my .json files (generated with dcm2bids) or not...
