What’s happening?
Customers are experiencing issues connecting to the Odata endpoint using Provar in the P-Test environment and Power Automate, resulting in errors such as "Unauthorized" and "The response object is null."
 

Reason:
This may arise due to: - Throttling of API calls to the Odata endpoint. - Incorrect configuration in the web.config file for the instance. - The 'IsPublic' property not being set to true for the concerned entity.
 

Resolution:

  1. For the Provar connection issue:
  2. Confirm which entity is being called by the API that is being throttled. Use the data explorer for Odata to identify affected entities.
  3. Check if the 'IsPublic' property has been marked as true for the concerned entity. If not, set 'IsPublic' to true and retry.
  4. Review the call method and ensure that the correct authentication method is being used.
  5. For the Power Automate connection issue:
  6. Update the web.config file as per the guidelines provided in the relevant technical support guide to resolve the "401 Unauthorized" error.
  7. Ensure that the correct realm value is set in the web.config file for the Secure OneBox instance.
  8. If the issue persists, consider reducing unauthenticated Odata calls to less than 10 calls over a 300-second window to avoid throttling.
