Should this go to the https://github.com/getsentry/sentry-dart repo? This seems like an SDK issue rather than something to do with issues.

[arc-yong]

any update on this? I face the same issue.

[buenaflor]

@arc-yong what sdk version are you using?

[toannmdev]

I faced the same issue
My sentry_flutter version is 7.13.1
This issue happens when my Sentry server is down.

@toannmdev this might be related to this fix getsentry/sentry-java#3200

try to upgrade to our flutter sdk >= 7.17.0 and see if this problem remains

[toannmdev]

utter sdk >= 7.17.0 and see if this

Thank you, Let me try this

[getsantry]

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you remove the label Waiting for: Community, I will leave it alone ... forever!
