openapi-generator generate --skip-validate-spec -i ~/Downloads/swagger.yaml -g rust -o scc-package-search

When calling https://openapi-generator.tech to botstrap some rust code, I get the following error

openapi-generator generate -i ~/Downloads/swagger.yaml -g rust -o scc-package-search
Exception in thread "main" org.openapitools.codegen.SpecValidationException: There were issues with the specification. The option can be disabled via validateSpec (Maven/Gradle) or --skip-validate-spec (CLI).
