Why is Chrome pausing on some line inside jQuery?

Question

Every time I refresh my web app with the Chrome Inspector open it pauses and takes me to the sources tab with a big red arrow icon pointing to some weird line inside jQuery.

I see

Paused in debugger

in the top-middle of the window, and

Paused on exception: DOMException

in the Call Stack on the sources tab.

As far as I'm aware, I haven't set any breakpoints and this code wasn't throwing exceptions before - so what's going on?

Answer 1

I had been debugging and forgotten to remove a breakpoint.

Answer 2

This can also cause the issue

Break Point icon at top left should be blue like this(For Deactivate BreakPoints)

Should not grey like this
