Common Causes

  • A dependent WebDAV operation in a batch failed first
  • Cascading failure in a multi-step transaction
  • Prerequisite operation returned an error

How to Fix

  1. 1Fix the root cause — the failed dependency — first
  2. 2Retry the entire batch operation after fixing the issue
  3. 3Check which sub-request failed and resolve it
