Hi Patrick,
Thanks for contacting Syncfusion Support.
We suspect that the error occurs due to the dataset field datatype mismatch with the query parameter. So, we request you to ensure both the dataset field and query parameters having same data type. If you still face any issue then we request you to share the report with dummy data to reproduce the issue at our end. It will be helpful for us to provide the solution at the earliest.
Regards,
Vinoth S.
