Report error in Dynamics AX

We had the following error while users were trying to print reports from AX.

The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:queryBuilderArgs. The InnerException message was 'Element 'http://tempuri.org/:queryBuilderArgs' contains data from a type that maps to the name 'http://schemas.datacontract.org/2004/07/XppClasses:SrsReportProviderQueryBuilderArgs'. The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver or add the type corresponding to 'SrsReportProviderQueryBuilderArgs' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer.'.  Please see InnerException for more details.

The problem goes away if you point the SSRS to another AOS through the AX client configuration or by restarting the AOS.
