I'm trying to import this Blueprint, and I'm not able to "preview" it. I'm getting an error:
found undefined alias 'error-message' in "<unicode string>", line 85, column 32: message: *error-message >- ^

I'm not sure how to go about resolving this. Is there a dependency requirement? (HA docker 2022.10.4)
