I keep getting "a field provided for filtering is not valid in that context" error message when using a column to query items in a list.

Question

I keep getting an error that says "a field provided for filtering is not valid in that context" when trying to filter a list of items. I have tried other fields and they work except for this specific one that is the most important query parameter.

I have directly copied the field name from the response when using only expand=fields as query parameter.
