Are you calling a post activity in Flow action of assignment which is doing Obj-Open. Sometimes we dynamically passing the parameters to Obj-Open or Obj-Open by handle that is sending null values at run time, which leads to such errors.

If not can you please tell little more details for reproducing this issue.
