Add Task -> Uncaught TypeError: Cannot read property 'data' of undefined

[Alex]

Hello,

https://dojo.telerik.com/@alexy99/acOsisiF

On Add task sometimes I get below, sometimes: Maximum call stack exceeded. As per below post I tried defaultValue for parentId but no go.

Hello Alex,

CRUD operations with remote data rely on server code to perform the read, update, create and destroy actions. To eliminate the observed error simply configure the DataSource's transport create and update actions as demonstrated in the below demo:

In addition to the above, you might also find the following article useful:
