Error deploying action Returned HTTP 503 (Service Unavailable) --> "Response Missing Error Message."

In the setup where an action index.js and its dependencies is zipped with :

const rtLib = require('@adobe/aio-lib-runtime')

rtLib.utils.zip(
  'dist/application/actions/pages-temp',
  'dist/application/actions/pages.zip'
)

adding const { Core } = require('@adobe/aio-sdk'); to the action and deploying it to runtime with aio app deploy --no-web-assets --no-build fails with the following error:

 ›   Error: PUT https://adobeioruntime.net/api/v1/namespaces/mynamespace/actions/actions/pages Returned HTTP 503 (Service Unavailable) --> "Response Missing Error Message."

if you are zipping without building the action, you are responsible for packaging its dependencies too.
Isn't this just a case of the dependency not being part of the zip?

No it seems like all dependencies are packaged but the sdk isnt able to find them.
