I'm attempting to do some testing with data from a Finance application, but for some reason the flow action for getting a record is saying that I need to provide the values for two keys for lookup, not just the item id (no clue why this would be a requirement). However, there's only one input in the action, and I don't know how to format a multi-key lookup.

(I deleted all the values for security reasons; when filled in, there's still only one box for Object Id).

The actual error message itself (I left the key columns out of the screenshot).
