		0 ignored issues – show Bug introduced 2020-02-10 15:21 UTC by Report Bug Copy Issue Report The type `Icewind\SMB\NativeState` was not found. Maybe you did not declare it correctly or list all dependencies? The issue could also be caused by a filter entry in the build configuration. If the path has been excluded in your configuration, e.g. `excluded_paths: ["lib/"]`, you can move it to the dependency path list as follows: filter: dependency_paths: ["lib/"] For further information see https://scrutinizer-ci.com/docs/tools/php/php-scrutinizer/#list-dependency-paths Loading history...

Did you maybe forget to handle an error condition? If the returned type also contains false, it is an indicator that maybe an error condition leading to the specific return statement remains unhandled. Loading history...
