TYPO3 Core

I´m sorry, it seems I looked at the wrong place. ParsedBody is not null and the suggest options work.

Instead there seems to be a problem with <pidList> causing the following error:

Argument #2 must be of type array, int given, in file vendor/typo3/cms-backend/Classes/Form/Wizard/SuggestWizardDefaultReceiver.php:115

Example code:

...
<suggestOptions>
    <default>
        <pidList>33,41</pidList>
    </default>
</suggestOptions>
...

Or maybe I'm missing some option for the usage with pidList.

I have also just come across this bug.

As Stefan Terborg already pointed out, the cause is vendor/typo3/cms-backend/Classes/Form/Wizard/SuggestWizardDefaultReceiver.php:115, which is this line of code:

$this->allowedPages = array_unique(array_merge($this->allowedPages, ...$availablePageIds));

The bug here is that $availablePageIds is a one-dimensional array. Therefore, the use of ... to pass the array values to array_merge is incorrect. The fix is to simply remove ...:

$this->allowedPages = array_unique(array_merge($this->allowedPages, $availablePageIds));

After doing this patch, the suggest wizard worked fine in my TYPO3 instance.
