TYPO3 generate wront path to show image in frontend after upgrading from v11 to v12

[agendartobias]

TYPO3 12.4.5
rte_ckeditor_image 12.0.2

I get error 404 that image is not found. Reason is that there is no / before fileadmin URL. So link looks like this:

<img alt="" class="img-fluid" data-htmlarea-file-table="sys_file" data-htmlarea-file-uid="4676" height="379" src="fileadmin/_processed_/7/f/csm_20220819_KANmyimagej_43d5e4676a.jpg" style="" title="" width="570">

It shoud be like this: https://mysite.si/fileadmin/_processed_/7/f/csm_20220819_KAN_avgust_2_Petra_Korenak__KGZ_Ptuj_43d5e4676a.jpg

If i go to BE and save the content element again it works but this is not a good solution

Update: i change this line:

t3x-rte_ckeditor_image/Configuration/TypoScript/ImageRendering/setup.typoscript

Line 7 in a372489

lib.parseFunc_RTE {

from lib.parseFunc_RTE to lib.parseFunc and it works
