This sentry?

[warjiang]

Yes, here is the sentry for open-source: https://sentry.io/for/open-source/

[warjiang]

The user reported the error stacktrace is hard to identify the problem, sentry will help us to parse the error stacktrace according to corresponded sourcemap

[warjiang]

Maybe we need extra config for whether to enable sentry, if users concered about the security problem, they can just disable the switch for sentry
