Bug Best Practice introduced by
The expression $segments of type string[] is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

Bug introduced by
The type Elgg\Http\UploadedFile 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
