Fellow Dev.....how do you resolve this problem... It keeps popping up.

Override alert() to return true
¯\_(ツ)_/¯

Have you tried using the network feature of the browsers development console to inspect the json data for dataTables?

I was getting this error sporadically, it was caused by a login timeout responding with a webpage to login again instead of the json data dataTables inspects.

You can also hook the error function and handle it in your own code instead of the alert box. I have an example somewhere if you need it.
