@DerekFurstPitt It's great that you used the CASE form to construct the returned fields. It worked well during my testing. Two changes I'd like to ask:

1. Add back hubmap_id field for Activity nodes. I noticed a rendering issue on portal-ui and reach out to John, he missed this field in his original list.

2. Constructing the fields programmatically instead of hardcoding them would make the logic more readable and give us a better control if later we'll add more fields. I put this code snippet as an example:

delimiter = ', '
enitty_properties = ['a', 'b', 'c']
cypher_pairs_list = [f'{x}: node.{x}' for x in enitty_properties]
cypher_pairs_str = delimiter.join(cypher_pairs_list) + delimiter
