Error edit category backend

[Yann]

I get the following error when I want to edit a category in the backend :

An error has occurred.
0 array_key_exists(): Argument #2 ($array) must be of type array, null given

Here is what is between line 190 and 199 of the "AssociationExtensionHelper" file:

public function getTypeTitle($typeName)
{
    $type = $this->getType($typeName);
   
    if (!\array_key_exists('title', $type)) {  
        return '';
    }

    return $type['title'];
}


If I comment on the "if" for the test, this solves the problem.
My problem is that it's the Joomla framework and I can't go hardcoding a solution. So how can I fix this officially ? Or do you have another explanation/solution ?

Thanks in advance for your help

If you change:

if (!\array_key_exists('title', $type)) { 

in

if (!\array_key_exists('title', $type ?? '')) { 

the error will be gone.

Do you have Associations enabled in Joomla? If you disable the “language filter” plugin, does the problem go away?

Wouldn’t that be modifying a core file? Is this a bug in the core files, or something wrong with the implementation of com_associations?

Thank you for your answers.

@seraphim
the change
if (!\array_key_exists('title', $type ?? '')) {
generate an error : "array_key_exists(): Argument #2 ($array) must be of type array, string given"
To solve the problem, I can comment this test, but I don't want to modify a Joomla file that may be replaced in the next update.


@Neo314
Yes it's a multi lang website.
So the plugin "System - Language Filter" and "System - Language Code" are enabled.

For the test, I deactivated these plugins and category editing worked again, without error.
I went further and tested the different options, and it's the option "Item Associations" that's the problem.

Hello

Problem is in line -> $type = $this->getType($typeName);

An error has occurred.
0 array_key_exists(): Argument #2 ($array) must be of type array, null given

$type must be array but its null;

Try to var_dump($type) or put

if (is_array( $type)) {

......

}else{

return '';

}
