Duplicate Document Key

What Happened

Each document within an envelope must have a unique key. The request included a document with a key that is already in use by another document in the same envelope.

How to Fix

• Use a unique key for each document in the envelope.
• Check the existing documents in the envelope to identify which keys are already in use.
• Update the duplicate key to a different, unique value before resubmitting the request.
• See the documents documentation for more details on document keys.
