如何让流体自动完成小部件在 TYPO3 v10 中工作

Question

I am trying to get the Fluid search widget autocomplete to work in my custom extension in TYPO3 v10. The problem is that I am getting the following error message when typing anything in my search field:

http://www.local-website.com/?id=2&type=7076&action=autocomplete&term=teststring - 500 (Internal Server Error).. After examining the exact response of that page request, here's the specific error:

"No widget context was found for the Ajax Widget Identifier "". This only happens if AJAX URIs are called without including the widget on a page"

Here's my Fluid autocomplete widget code as I have implemented in my extension's Fluid template:

<f:widget.autocomplete for="search-items" objects="{allItems}" searchProperty="title" storeSession="false"/>

I have not set up anything specific for AJAX (ie I have not set up page type 707 as I would not know how to do this)...

Here's the widget information page I'm using: https://docs.typo3.org/other/typo3/view-helper-reference/10.4/en-us/typo3/fluid/latest/Widget/Autocomplete.html

This happens if the new parameter storeSession="false" is used. In TYPO3 v9 this parameter didn't exist.
Using the widget like this should work like intended:

<f:widget.autocomplete for="search-items" objects="{allItems}" searchProperty="title"/>

Usually the parameteres look like this:

?id=1&type=7076&fluid-widget-id=9c31f0bb1b5f5f953e84f6b57af102b4&action=autocomplete&term=Ma

When the parameter storeSession=false is used it looks like this:

?id=1&type=7076&action=autocomplete&term=Ma

That means that the widget doesn't transfer the correct link to the AJAX script.

The issue with the parameter storeSession is clearly a bug but I never expect that this will be still fixed in the official TYPO3 v10 as widgets are in general removed in TYPO3 v11 already.
Nevertheless I reported it and it can be found here: https://forge.typo3.org/issues/98173
