I cannot find where the exception is due to the information

the exception is:an error occurred while calling tracking participants causing the instance to be oborted.See the inner exceptionfor more details.
exception type: OperationCanceledException

i met the exception when i used “build datatable” activity, but i don’t think there is an error,maybe the error occurerd before the activity,when i used invoke work file activity.but no exception was informed during that process.the phenomenon is the uipath just paused for a verrrrry long time when it was running,after sevel minutes,the exception i mentioned above was alerted. so when should i search my error? thank you very much

Can you share the workflow ?
