Exception in combination with Solr extension scheduler task (Argument #1 ($site) must be of type ApacheSolrForTypo3\Solr\Domain\Site\Site, null given)

[localhorst]

Hello, we are getting fatal errors on the command line when both these extensions are installed:

apache-solr-for-typo3/solr
werkraummedia/abtest

The error occurs when starting the solr indexing scheduler task from command line. It seems that the FrontendController must not be modified to initalize Solr index service (getInitializedIndexService). The error does not occur if the task is started manually from the backend.

foo@bar-web:/var/www/html$ vendor/bin/typo3 scheduler:run --task=5 

Uncaught TYPO3 Exception ApacheSolrForTypo3\Solr\Task\IndexQueueWorkerTask::getInitializedIndexService(): Argument #1 ($site) must be of type ApacheSolrForTypo3\Solr\Domain\Site\Site, null given, called in /var/www/html/htdocs/typo3conf/ext/solr/Classes/Task/IndexQueueWorkerTask.php on line 75
thrown in file /var/www/html/htdocs/typo3conf/ext/solr/Classes/Task/IndexQueueWorkerTask.php
in line 207

Unfortunately, no more info about this error was logged. But I was able to determine the culprit with Xdebug.

I created a pull request for this error here.
#3
It works on our machines (DDEV/nginx and Production+Staging on Apache2, both PHP 8.1)

I guess the AB-Test hook is not needed in the CLI anyway.
Probably it can be disabled for the backend as well.

@svewap @d-s-codappix Hi Daniel & Sven, could you have a look at this?

[svewap]

@localhorst I'm sorry, but I don't currently have a contract that would allow me to spend the time on this.

[localhorst]

Thanks anyway. Maybe @koritnik could merge (and test) this?

Thanks @localhorst for pinging me. I'm not watching the repository of our customers.
I've provided feedback within your PR.
