Error: Geodatabase Data Type Mismatch when trying to submit related record in Esri Field Maps

Hello, I have two related tables related to my water hydrant feature class. So two relationship classes to the hydrant and the tables are hydrant inspections and flushing. When I upload the data to arcgis online and try to submit a related record form to the table in Field Maps, it tells me "Geodatabase dara type mismatch". I cannot figure out what is going on. Anyone have any ideas? Attached is a screenshot of the error I got when trying to test out the tables.

Yes. The problem was that the field that I was using to relate the table to the feature service was a different data type in the table vs. the feature class. 

Flush ID Field in Hydrant Feature Class: Double

Flsuh ID Field in Hydrant Inspection Table: Text

So one had to be changed so that they both had the same data type.
