initiateStopPayment REST API gives an error - Cannot create an object of type

Summary:

The REST API initiateStopPayment works fine in SOAPUI for payment of one Business units, but it does not work for an another Business unit.

When I invoke the REST API, it gives HTTP/1.1 400 Bad Request and this error:

Cannot create an object of type:java.lang.Integer from type:java.lang.String with value:123456789

where: 123456789 is the payment number passed in JSON Body.

We provided the Data Access for the roles for both the Business units.

Any setups further to check ?
