Enabling CMK on Fabric Workspaces

Hi, the key is RSA 2048 and I did try your suggestion, but it did not fix the issue, still get the exact same error message.

To be honest, I'm not 100% convinced you would be setting this role at the key level. As per the guide; Fabric only supports versionless customer managed keys, from the guide... Fabric checks the key vault daily for a new version, and uses the latest version available... 

This would indicate to me that the role should be set at the key vault, otherwise as soon as a new key is present all access would stop until the role was manually assigned to the new key. In addition, the guide does explicitly state that the role should be set at the key vault, prior to the creation of the RSA key.

Thanks for your suggestion though, it was worth a try.
