The type
WebStream\IO\length 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. filter:
dependency_paths: ["lib/*"]

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:For further information see https://scrutinizer-ci.com/docs/tools/php/php-scrutinizer/#list-dependency-paths
