Sorry, it would not be feasible to access the link as I am using the plugin on our company’s intranet which can be accessed only by the employees.
But on more analysis I have figured out it indeed is a javascript error. We were able to use the explorer view without any issues.
Also, I managed to add an extra feature to the explorer view. To download a whole folder which was needed for our use. If it would be useful, I would be glad to share the addition with you.
