To update a picklist value I'm referring to the metadataclass.cls
I'm calling a class method (as like in metadadataclass example) to update the picklist value via a trigger (class method set to
@Future(callout=true)) which seems to work but in the log i get an error as below:
Web service callout failed: WebService returned a SOAP Fault: INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session faultcode=sf:INVALID_SESSION_ID faultactor=
Please any help on to fix this error so that i would be able to update the picklist value for the picklist list (custom field)?
