After following this link:

Hi Abdelrhman Hiba,

I think you are getting this error from this line

custObj = CLRInterop::getObjectForAnyType(custContract);

if so can you check if custContract is Null?

If CustTable has no rows, custContract will be Null, this might be the cause.

CLRInterop::getObjectForAnyType Converts a value of the X++ anytype data type to a value of the CLRObject data type.

You mentioned that you are testing the code in a job, a job executes on client, X++ CIL is on AOS.

The reason you are getting this error is because you Execute a job that calls CLRInterop::getObjectForAnyType on client.

Hi Abdelrhman Hiba,

Web services and batch jobs run in CIL, and the CIL generated from X++ exists only on AOS.

So the CLRInterop::getObjectForAnyType only work in AOS, it will throw the error if you call CLRInterop::getObjectForAnyType directly from the AX client.
