This error typically indicates a mismatch between the parameters defined in your mashup and those being passed to it. To troubleshoot:
Check Mashup Parameters: Ensure that the parameters you are trying to bind in your mashup are correctly defined. Verify that the names and types of the parameters match what is expected in the mashup configuration.
Review DataTable Binding: Confirm that the DataTable is correctly set up and that the data structure aligns with the expected input for the mashup parameters.
