How to solve Action Timed Out error?

Hi all,

We have a pipeline scheduled to run at night and there have been many timed out errors. The dataflow usually only takes only 7 minutes but it failed after 2 hours by timing out. But it is sucessful when re-ran and the dataflow took only 6 min 45 sec. I can only see below details. 

The dataflow has source as table in databricks and target as synapse. Source has 198K records and target has 82.1M. What can be the cause?
