M2.2.x: Script error for wysiwygAdapter

ISSUE:

We are facing one issue:

- Creating a pop-up

- Content and Design tab

- Load template button - nothing happens, no templates load

- Script error for wysiwygAdapter:

SOLUTION:

On M2.2.11, the tinyMCE doesn't need to use wysiwygAdapter while the module is declaring wysiwygAdapter, which leads to an unexpected error and makes the button's click action not be run. 

To resolve the issue, please remove "wysiwygAdapter" declaration in line 20 in the file app/code/Bss/Popup/view/adminhtml/web/js/type_template.js:

However, please note that, from Magento 2.3.x, the tinyMCE will use and declare wysiwygAdapter, so it is necessary to add "wysiwygAdapter" again into the file app/code/Bss/Popup/view/adminhtml/web/js/type_template.js
