TypeError: strlen(): Argument #1 ($string) must be of type string, array given in strlen()

Hi @ramu_bharu,
I have resolve this issue "TypeError: strlen(): Argument #1 ($string) must be of type string, array given in strlen()" and also attache patch ,
kindly review and verify .

@grevil: Could you also take a short look at this, before we tag a new D11 compatible release?

Should be a MR and code style seems to be wrong

I've added a custom attribute of type formatted text [...]

There is no form element of type formatted text / formatted_text, see https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Render%21... for a full list of all form elements. Did you mean to add a field of type textfield / textarea? But of course, a wrong type shouldn't throw an error. I'll take a look.

Can not reproduce this issue. Using the incorrect "formatted_text" type, simply doesn't render the form element as expected. Maybe the indentation of the configuration throws an internal YAML error which isn't catched?

@ramu_bharu, could you give us further information to reproduce?

PHP Version, Drupal Version, Your configuration in (/admin/config/menu_link_attributes/config).

I have this same error.
I installed latest version of all: Drupal 10.3.2 / PHP 8.2.12 / 10.4.32-MariaDB

It is triggerd when i use a special character (unicode), in casu ê in the input field that is provided by a URL parameter like :...?parm=être

Thanks @setki!

Could you share your configuration in "admin/config/menu_link_attributes/config" and provide clear steps to reproduce?
