HiAnonymous ,
Please check if it is caused by the following reasons ：
1.Mismatch between the data types of the keys used in relationships.
2.Improper date formats of the date fields in relationships.

Make sure the data types of both the fields in a relationship are same. replace (null) values with 0 for decimal or whole number data types.
For more information，you can refer to this ：Error-the-exception-was-raised-by-idatareader-interface/
If it doesn't work, please let me know.
Hope it helps.
