the error is correct
because i do have a mix of meta.yaml and recipe.yaml files

$ git checkout add-i2pd
$ ls recipes/*/*.yaml
recipes/example/meta.yaml
recipes/example-v1/recipe.yaml
recipes/i2pd/meta.yaml
recipes/miniupnpc/meta.yaml

but the error is wrong
because recipes/example-v1/recipe.yaml is part of the main branch

$ git checkout main
$ ls recipes/*/*.yaml
recipes/example/meta.yaml
recipes/example-v1/recipe.yaml

this should be

example-v1
example

... to list all directories in recipes which are tracked by the main branch

so both linux and osx CI runners are wrong
(but why does this work most of the time?)
