It seems like $keys of type array is incompatible with the declared type Bdf\Prime\Relations\Util\list of property $keys.

        $this->entity = $entity;
    }

        $this->entity = $entity;
    }

    /**
     * Get the attached entity
     *
     * @return mixed
     */
    public function get()
    {
        return $this->entity;
    }

    /**
     * Compute the hash on keys for make a simple hashmap

     */
    public function hash(): int
    {
        if ($this->hash !== null) {
            return $this->hash;
        }

        $hash = 0;

        foreach ($this->keys as $pos => $key) {
            $hash ^= ($pos + 1) * crc32($key);
        }

        return $this->hash = (int) $hash;
    }

    /**
     * Check if the two keys are same or not
     *
     * @param EntityKeys $other
     *
     * @return bool
     */
    public function equals(EntityKeys $other): bool
    {
        return $this->keys == $other->keys;
    }

    /**
     * Get the keys value to array
     *
     * @return string[]
     */
    public function toArray(): array
    {
        return $this->keys;

The expression return $this->keys returns the type Bdf\Prime\Relations\Util\list which is incompatible with the type-hinted return array.
