I’ve got a structure field with just a textarea field inside.
In a hook, I create a subpage and use the text entered by the user in the textarea as a title for this subpage.
When saving my change in the panel, I’ve got this pop-up error:
The form could not be saved
Exception: Whoops\Exception\ErrorException
mkdir(): File name too long
For instance, it occurs with a text of 337 characters
