I am in the process of trying to resolve depricated code for mega module to get it to work better with drupal 8.8 and up.

In the process I am getting this error below from file AweMegaMenuForm.php  

InvalidArgumentException: The URI ‘awe_builder.admin.place_block’ is invalid. You must use a valid URI scheme. in Drupal\Core\Url::fromUri() (line 282 of /var/www/wp-dev/core/lib/Drupal/Core/Url.php).

Do you have a possible solution for error above? 

and any chance you have an updated version of mega menu module to better support drupal 8.8 or newer. 

Any help would be greatly appreciated. 

Thank you
