$builder is always a sub-type of JuliusHaertl\PHPDocToRst\Builder\FileBuilder.

$builder->getFile() is always a sub-type of phpDocumentor\Reflection\Php\File.

The method getLocation() does not exist on phpDocumentor\Reflection\Element. It seems like you code against a sub-type of said class. However, the method does not exist in phpDocumentor\Reflection\Php\Namespace_. Are you sure you never get one of those?

            $url = $this->getGithubLink($filePath, $lineNumber, $this->branch);
            $builder->addFieldList('Source', '`' . $filePath. '#' . $lineNumber . ' <'.$url.'>`_');
