Clean DocumentDB setup fails indexing

Clean DocumentDB setup fails indexing

Description

Source [Link Removed]

The user has encountered the error log:
MongoDB.Driver.MongoCommandException: Command createIndexes failed: Implicit collection creation not supported when creating indexes

It potentially has to do with a DocumentDB from clean edge case.

Steps to Reproduce

Extrapolated from UDN:

  • Setup new horde server (AWS ECR - for reference)
  • Setup a DocumentDB database to use; clean (no incremental)
  • Start the horde server
  • Server log shows multiple:
    • MongoDB.Driver.MongoCommandException: Command createIndexes failed: Implicit collection creation not supported when creating indexes
