The expression
return $this->start * $this->step ** $index returns the type integer which is incompatible with the return type mandated by Smoren\Sequence\Interfac...face::getValueByIndex() of Smoren\Sequence\Interfaces\T .
In the issue above, the returned value is violating the contract defined by the mentioned interface. Let's take a look at an example: interface HasName {
/** @return string */
public function getName();
}
class Name {
public $name;
}
class User implements HasName {
/** @return string|Name */
public function getName() {
return new Name('foo'); // This is a violation of the ``HasName`` interface
// which only allows a string value to be returned.
}
}

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
