Broken swagger:response Generation with Go 1.22.0 + 1.21.5 darwin/arm64

Problem statement

I've been trying to get Swagger running for a few hours now. I can't seem to get responses working at all. Using code directly from the example page (https://goswagger.io/use/spec/response.html):

// A ValidationError is an error that is used when the required input fails validation.
// swagger:response validationError
type ValidationError struct {
    // The error message
    // in: body
    Body struct {
        // The validation message
        //
        // Required: true
        // Example: Expected type int
        Message string
        // An optional field name to which this validation applies
        FieldName string
    }
}

And building with swagger generate spec -o ./swagger.yaml (also tried swagger generate spec -o ./swagger.yaml --scan-models), I get this output:

responses:
    validationError:
        description: A ValidationError is an error that is used when the required input fails validation.

No amount of anything seems to fix this from what I've tried.

Any help would be greatly appreciated!

Environment

swagger version: v0.30.5 (I've tried static builds + homebrew)
go version: 1.22.0 + 1.21.5
OS: darwin/arm64

Also tried Docker, couldn't get it working. Hit way too many issues worth my time, already spent wayyy to long trying to get this working.
