After upgrading to Joomla 4: unable to edit old items

Hello,

I just upgraded one website from J3.5 to J4. Everything went perfectly but I didn't mentioned that we couldn't edit the olds items every time I edit one item, I get this error:

Joomla\Filter\InputFilter::__construct(): Argument #1 ($tagsArray) must be of type array, null given, called in /home/customer/www/domain.ext/public_html/libraries/src/Filter/InputFilter.php on line 69

If I create a new item, I can use it edit it etc.

I looked at the tags field and it seems searching all the time. (maybe that helps)

Any idea why?

Could you open an issue in github ?

can you send me an access ? and url to test an item ?

PM sent.

Hi,

I am coming back to see if you found a solution as we are reaching my limit in time to recover from an old backup.

sorry for now no time to investigate i will try

I have exactly the same problem on new or old item. When I do a modification and "save and close" I have the message :
Une erreur est survenue

0 Joomla\Filter\InputFilter::__construct(): Argument #1 ($tagsArray) must be of type array, null given, called in /home/whoswort/www/lesunimog_fr/libraries/src/Filter/InputFilter.php on line 69

If I choose only "Save" (without close) I stay in a infinite loop

can you check your image field and disable Intro / Full support
that correct it ?

All my image fields are "Reutilisable (mode DB)" not "Joomla article image (intro + Full)"...
Your question is about that ?

I have some error messages in my image fields :
