JsonView backend module error

[do-web]

If try to open the JsonView Backend Module i got an error:

` FriendsOfTYPO3\Headless\Utility\FileUtility::getNormalizedParams(): Return value must be of type TYPO3\CMS\Core\Http\NormalizedParams, null returned

in /var/www/html/public/typo3conf/ext/headless/Classes/Utility/FileUtility.php line 251

protected function getNormalizedParams(): NormalizedParams
{
    return $this->serverRequest->getAttribute('normalizedParams');
}

`

It seams that $this->serverRequest->getAttribute('normalizedParams') is null.

Hi @do-web, could you provide more context? TYPO3 version, headless version, and some steps to reproduce it?

I'm closing issue as this functionality was moved to https://github.com/TYPO3-Headless/headless_dev_tools package cc @lukaszuznanski
