Action does not give a warning or error if it cannot find the OverrideArmParameter file specified.

Using operation 'validateDeploy' the action does not give a warning or error if the override arm parameter file specified is not found.

Instead the Action completes reporting successful, but has not picked up the overrides and deployed with the source workspaces settings.

It would be better if action could give a warning like it does when it can't locate the template-parameters-definiton.json file, so it is clear to the user it did not find the OverrideArmParameter file specified.

Start with the validateDeploy operation and trace how the specified OverrideArmParameter file is located and handled. Compare that path with the existing warning for a missing template-parameters-definiton.json file; done means a missing override file produces a clear warning or error instead of reporting successful deployment without the overrides.
