I have configured a Nintex workflow with a Nintex Form & several Workflow Task forms.
For add/modify/view, Nintex form is using an API to query a remote DB and Task form just use SP query.
The problem is when i tried to open the tasks forms or the Nintex form, the form doesn't open and remains in the loading screen. This happens in all the browsers. But sometimes it works in some and others don't.
We tried to open the tasks from a rollup webpart as well as directly from Workflow tasks. The issue is same.
When checking the developer tools, the code is not executed completely as shown in the below screenshot,
Also the console show errors like "NWF$ is not defined", please refer the below screenshot,
Kindly provide solution for this issue asap, will be much appreciated
