We are using PCS framework. Now in PCS framework when Plan instance is approved, an activity SaveUnionDataRules is queued(asynchronous execution) to create Rule-HC-PCS-UnionData instance for the Plan.

Now our requirement is to auto approve approve the plan through Agent. Now when the activity SaveUnionDataRules gets queued, and wakes up in a different requestor, we are getting exception from Rule-.StandardValidate activity that RulesetContext cannot be obtained(Step 2).

Below is the Stack Trace:

Note: When any user manually approves the Plan, the Rule creation using the same steps works good.

Can anyone pls help on how we can mitigate the exception.
