the yml schema doesn't complain so this is either an issue in rattler-build or in the schema.

Can you make it a list and try again?

[pavelzw]

yes making it a list fixes it. the yaml-schema doesn't complain, though.

[wolfv]

For me, this is a schema issue as the patches should be a list of strings. @zelosleone you can take a look at this in the https://github.com/prefix-dev/recipe-format

[wolfv]

Schema was updated :)
