A single error detail entry describing one part of a failed change history request.

## Declaration

object ErrorMessage.Details
```

## Discussion

Discussion Each entry in ErrorMessage’s details array narrows down which part of the request caused the failure. Use these entries, together with the top-level message, for diagnostic logging or user-facing error displays. Use the top-level code on ErrorMessage for programmatic error handling. Example {   "code": "MISSING_FIELD",   "message": "eventTime must be provided.",   "info": {     "field": "eventTime"   } }
