Hi @arularputharaj do you know what version of marionette you have? I have v3.5.1 and is working ok

After updating correct version (Backbone.Marionette v3.5.1) UI working,

but unable to send message, I am getting the below mentioned error.

Error: Call to a member function addMessage() on null in Drupal\private_message_messenger\MessengerHelper->saveMessage() (line 513 of /var/www/html/flexforce/modules/Private-Message-Messenger-master/src/MessengerHelper.php).

I can confirm using Marionnete v 3.5.1 solves the issue for me.
