Time stamp & array passed in a cluster through DLL are not accepted by Teststand

I am trying to pass  Timestamp & array data [string array]   in a cluster  from DLL  is not  getting recognized by testsand.

The action module (DLL)  Output (cluster)  generates   error "System Level Exception.[Error Code: -17502] "

the png file shows the cluster

I spoke to NI support & they  suppose that its time stamp that generates error

but some fields (numeric, string) i am able to read
