BIDS validator unable to detect existing metadata fields

I am using the online BIDS validator (v1.9.3) and it’s unable to read metadata fields like ‘RepetitionTime’, ‘TaskName’ for EPI data and ‘PhaseEncodingDirection’, ‘ReadoutTime’ for fieldmap data. These fields are present in the corresponding .json files.
Any ideas on what might be going wrong are appreciated.

Here is a screenshot of the error

Here are snippets from the epi .json

and a couple of snippets from the fieldmap .json
