I am trying to create Tasks in Sales Cloud, from within a Marketing Cloud journey, but sometimes it doesn't succeed. In one instance, the journey creates 100 tasks, but another 9 fail due to 'Soft Error'. There is no Status Detail.

Looking at the Contacts, for which the tasks are supposed to be created, I cannot find anything wrong, they look just like the other Contacts for which tasks could be created.

Where can I find more detail on why these task creations are failing?

Ask SF support - they can review the backend error logs, but it might be a lot data for them to sift through.

I have heard about errors like this and at times it was due to CPU overload of the connected SF org, for example:

System.Exception: message = "TaskTrigger: System.LimitException: Apex CPU time limit exceeded", statusCode = "CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY"

If this would be the case, try adding wait steps and random splits before the Task creation activity - this should attempt to create smaller numbers of Tasks simultaneously, reducing the CPU load.


I don't think it's possible to look up the exact error message anywhere, but according to the documentation, you can try troubleshooting using this information:

Runtime Errors

Runtime errors occur when a contact enters an activity in a running journey. In some situations, these contacts aren’t processed correctly. It is difficult to detect these errors because Sales and Service Cloud activities in Journey Builder use soft errors. A soft error does not stop the contact from continuing through the journey. Here are some common runtime errors.

  • Missing or deleted objects: When an object referenced in the activity is no longer available after the journey is activated, the activity cannot complete its function.
  • Row-locking: Some objects, especially CampaignMember, can time out when a contact record locks and the operation stalls.
  • Failed Lookups: Sales and Service Cloud activities include options for how to proceed when a lookup fails to find a contact record. However, it is possible that the lookup request can fail during processing. When the request fails, the activity errors, but the contact continues in the journey.
  • Required Fields: If the selected attribute for a required field is empty, the activity errors.
