A Job scheduler is set to run at a particular time every day and it is failing randomly (atleast once in a week) with an exception like shown below. The activity referred in the job scheduler ran successfully on a manual attempt (after the failure scenario). Can anyone throw some light on this issue, below is the stack trace,

@MarcLasserre_GCS - This is happening only in Production environment and there is no way to trace it as the issue is not occurring consistently. Once in a while the job fails and users report that they are not seeing the expected values on the report. Moreover, once a failure is reported, when the same job scheduler is ran manually it worked fine always.

Here is another error seen on the same job, when we ran the activity configured in the job manually it worked fine.

We are unable to figure out if this is a database issue or code issue, also the below exception occurred on 250 case instances (as seen in PDC). When tried to query PZPVStream column in database none of the rows returned null, so not sure what could be the reason for this issue. Please help.
