Kendo template error on initialization

[Jaanus]

Kendo gives me error and fails to load components during startup. I am using kendo version 2018.3.911.

 

This is the error I am getting.

kendo.all.js:232 Uncaught Error: Invalid template:'<div class="k-group-indicator" data-#=data.ns#field="${data.field}" data-#=data.ns#title="${data.title || ""}" data-#=data.ns#dir="${data.dir || "asc"}"><a href="\#" class="k-link"><span class="k-icon k-i-sort-${(data.dir || "asc") == "asc" ?

Hello Jaanus,

May I ask you to prepare and send us a small runnable sample that replicates the error observed? You could use the Dojo sandbox to prepare the demo. This way we will be able to troubleshoot the problem locally.

Solved it on my own.

 

It seems that some CSRF policies were breaking kendo.
