Sentry pings the URL's in the errors, creating more errors

I have some javascript errors like these:

The issue that I’m seeing sentry fetching the page from the error, after it has been reported, creating extra load and sometimes more errors, leading to cascading errros: - - [19/May/2017:11:22:09 -0500] “GET /registration?coupon=GIMME5&commit=Apply+Now HTTP/1.1” 200 13354 “” “sentry/8.13.0 (”

How do I stop sentry from doing those requests from errors?

I think I’ve found the setting that disables that per project. It a checkbox with the text “javascript source fetching” or something like that.
