The atlas-run-cloud command is no longer the supported method for developing a cloud add-on as per the blog Atlassian introduces new cloud development environment.
The command should be deprecated to remove confusion around the correct method for developing for Atlassian Cloud products.
Remove all references to RunCloud functionality within AMPS.
If you're looking do develop a cloud compatible add-on, please check out the https://developer.atlassian.com/docs/
