Hi,

For error related to Invalid server response:
Full Exception: UiPath.Shared.Activities.CorrelationIdException: Request CorrelationId: (ID is being showed here)
Invalid server response. —> UiPath.DocumentUnderstanding.ML.Activities.Exceptions.MLRequestException: Invalid server response. —> System.Exception: Response status code does not indicate success: 404 (Not Found).

RCA: Please find the below steps:

  1. In DU under Extract work flow >> Data Extraction scope >> Machine Learning Extractor >> Configure Extractors >> Settings
  2. End Point and API Key are used to get capabilities of latest ML Skill.
  3. Make sure you are pointing to the latest ML skill manually every time you are creating a new pipeline.
  4. If the configuration is already pointing to latest using asset values for “End Point”, make Sure the check box is un-checked for “Update Activity Arguments”. If it is checked the hardcoded values “The old values” was used by the bot even if you are using config. to pass the values from assets.
