Local feature fails with unspecified options

Hi,
I’m in the midst of development so the features I’m composing into a devcontainer are local. This works when running in vscode.

When running with en builder I get an error that the options my devcontainer.json is specifying are not valid for the feature. I haven’t tested this yet with remote features but I’m assuming this is because they’re local because the devcontainer compatibility doc says options are supported.
