Problem/Motivation
After Updating from 8.x-1.1 to 8.x-1.2 drupal admin page config displayed this:
/** * @file * Installation actions for menu_markup. */ /** * Implements hook_install(). */ function menu_markup_install() { // No specific installation actions required. } The website encountered an unexpected error. Please try again later.
(with a stack trace)
Dblog had this stack message: (not sure if any other pages were affected, I downgraded back to version 1.1 before checking other areas and read through the logs.)
RuntimeException: Failed to start the session because headers have already been sent by "/var/www/html/web/modules/contrib/menu_markup/menu_markup.install" at line 1. in Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage->start() (line 152 of /var/www/html/vendor/symfony/http-foundation/Session/Storage/NativeSessionStorage.php)

Steps to reproduce
Composer update to latest version, then drush updb and drush returned database update required for menu_markup so I said 'yes' and then followed with drush cr now go to ../admin/config page (broken) with above listed response..
The site this occured on is running Drupal 9.5.10, PHP 8.1.13, Apache/2.4.38
I haven't looked any further into the cause - however I did notice when I ran drush updb this module triggered a notice to update db with "/** * @file * Installation actions for menu_markup. */ /** * Implements hook_install(). */ function menu_markup_install() { // No specific installation actions required. }" reported by drush (as stated above I said yes to update) so I'm "thinking/guessing" the newly included code implementing hook update or somewhere else in the .module file (perhaps syntax) is where the problem lies! If I get anytime (unfortunately it likely would not be anytime soon) I'll try to figure out what happened and offer a patch if I can.
If you need any other info please let me know!
