2 month ago, after an upgrade of raven-js > 3.23 (https://github.com/getsentry/raven-js/releases/tag/3.23.0) I started receiving errors as noted in the release note.
The error is hard to debug: the message is
undefined and the stack is (raven-js 3.25.2)
at _promiseRejectionHandler([native code])
The breacrumb does not help me to debug (I can’t find a pattern that trigger the error). However I noticed that this error happens 98% on iPad.
How would you do to debug this error?
Thanks for your help,
