AX 2012 Report Error

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.



Solution

Check the Temp files in you AOS server locations and try by deleting them.

C:\Users\AOSAccount\AppData\Local, Delete the all the AUC and KTI files.

C:\Users\venkatesh.vk\AppData\Local\Microsoft\Dynamics AX\VSAssemblies

Stop and start the service.

I din't need a CIL since i was sure that there were no changes made in the environment.
