Extremely long delays when reporting errors with a long message #2286

Description

Package + Version

@sentry/browser

Version:

5.6.3

Description

I'm using mobx-state-tree, which generates very long error messages, when trying to instantiate a model with data that doesn't match the defined schema.

It appends a full dump of the the data to the message, among other things.

I've seen it generate a 300kB message from a 10kB JSON payload.

When calling Sentry.captureException(error), I notice delays around ~90s.

The issue seems to originate from Tracekit, and particularly from a RegExp which is ran on each line of the stacktrace (which includes the message).


I've also opened an issue on Tracekit repo. I opened one here too, because the dependency is duplicated in your repo too.
