"Unable to perform the requested operation..." or "Request validation failed" error when provisioning Omnichannel

This article provides a resolution for the issue where an error occurs when you provision Omnichannel for Customer Service.

Symptoms

When you provision Omnichannel for Customer Service, one of the following error messages appears:

Unable to perform the requested operation due to lack of permissions

Request validation failed. Failed to execute action in CRM for selected environment

Cause

The user is either logged in as a System Administrator on a child business unit (instead of the root business unit), or they don't have read privileges for system roles.

Resolution

To resolve this issue:

• Check the permissions for the user, and change the business unit of the system user to the root business unit.
• Ensure that the user is assigned at least one security role (preferably Omnichannel Administrator) other than the System Administrator role.
