It happens sporadically, can't find a perfect reproducible way yet, but saw it happening sometimes upon subscription after app crash.
It seems to have started happening again after updating camera firmware and autopilot. The same way the new firmware fixed the setSettings issue, it has brought this issue back. So, not sure who to go to to fix this.

[douglaswsilva]

@julianoes and @JonasVautherin Can you guys take a look at this when you have a chance. We've been getting it pretty often. Here are the logs we have:

com.3dr.site-scan_issue_crash_2b4f63d856f348bc99285854652edd9d_DNE_0_v2.txt
com.3dr.site-scan_issue_crash_b7426f7b457f40e39884e53b6164dfa9_DNE_0_v2.txt

[julianoes]

@douglaswsilva thanks for the bump. I will look into this ~today~ tomorrow. Maybe I can blame the camera firmware update, however, the SDK should still not crash because of it!

[julianoes]

@douglaswsilva I have pushed a potential fix #746. It would be nice if you could test it and see if it fixes the crash.

[douglaswsilva]

Will do next week. Thanks Julian!

[JonasVautherin]

@douglaswsilva: Please reopen here if #746 doesn't solve it :+1:.

[douglaswsilva]

Thanks @JonasVautherin . I still haven't had time to get to this, but plan on testing it soon. Is it included in Eddie?

[JonasVautherin]

I don't think it is in 0.16.0. I can try to make a new release soon (like next week).
