Upgrading successful, cannot access Action Center via Load Balancer URL

Remedy:

  1. In the ActionCenter/Actions/environments/env.json key, manually update the values for businessUserPortalProxyServiceUrl and postLogoutRedirectUri to the correct load balancer URL.
  2. In the ActionCenter/Processes/environments/env.json key, manually update the values for businessUserPortalProxyServiceUrl and postLogoutRedirectUri to the correct load balancer URL.

Upgrade successful, cannot access Action Center

Description: After upgrading Action Center from 2021.4 to 2022.10, the access is blocked by the CORS policy.

  • Event log error - IdentityServer4.Hosting.CorsPolicyProvider CorsPolicyService did not allow origin.
  • Console error - Access to XMLHttpRequest at '<changed_action_center_url>/actioncenterservice/feature/features/ActionApp' from origin '<action_center_url>' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header has a value '<action_center_url>' that is not equal to the supplied origin.

Cause: The Action Center URL changed its value inside the Registry after upgrading to a higher version.

Remedy:

  1. Update the Action Center URL with the correct value for Actions:

    • Go to the ActionCenter/Actions/environments/env.json file path.
    • Change the value for action_center_url inside the "businessUserPortalProxyServiceUrl" key.

      The format for the "businessUserPortalProxyServiceUrl" key is <actioncenter url>/actioncenterservice.
    • Change the value for action_center_url inside the "postLogoutRedirectUri" key.

      The format for the postLogoutRedirectUri is <action_center_url>/actions.
  2. Update the Action Center URL with the correct value for Processes:

    • Go to the ActionCenter/Processes/environments/env.json file path.
    • Change the value for action_center_url inside the "businessUserPortalProxyServiceUrl" key.

      The format for the "businessUserPortalProxyServiceUrl" key is <actioncenter url>/actioncenterservice.
    • Change the value for action_center_url inside the postLogoutRedirectUri key.

      The format for the postLogoutRedirectUri is <action_center_url>/processes.

Access to XMLHttpRequest has been blocked by CORS policy

Description: You're using Orchestrator storage buckets, and when you try to access document validation actions, the following errors are thrown:
  • Could not connect to the server
  • An error occurred while retrieving the DOM (Document Object Model)
Cause: The <cors> section in Orchestrator's web.config file overrides the Action Center URL that you input in the "AcceptedRootUrls" key from the UiPath.Orchestrator.dll.config file.
Remedy: Perform the following steps to fix the issue:
  1. Open the web.config file from Orchestrator.
  2. Find a section that contains <cors>.
  3. If this section exists, then add the Action Center URL in this section, as well.
