hi
The error message you're seeing ("The resource with id does not exist") typically indicates that the system is unable to find the object that you're trying to reference. This could be caused by a variety of issues, including incorrect object IDs, missing dependencies, or other configuration issues.
Here are a few troubleshooting steps you can try:
Check the object IDs: Double-check that the IDs you're using for the app, business unit, and security role are correct. Make sure that the IDs are in the correct format and match the IDs used in other parts of the system.
Verify dependencies: Make sure that any required dependencies are installed and configured correctly. For example, if the security role relies on a custom entity or field, make sure that those are also set up correctly.
Check permissions: Ensure that the user account you're using to create the application user has the necessary permissions to create users and assign security roles.
Try a different browser or device: Occasionally, browser or device issues can cause errors like this. Try creating the application user using a different browser or device to see if the issue persists.
