When not using disk buffering, it works without problems:
// .setDiskBufferingConfig(diskBufferingConfig) on line 37 of OtelDemoApplication.kit

Hi, @rogierhofboer

Thank you for the feedback. This issue was recently sorted upstream. So once we bump the upstream version, it should get sorted here.

I just tried this on the tip of main with the demo-app and could not reproduce it. Logs were flowing into the collector, and no exceptions were noted in logcat. Please reopen if this is still a concern. Thanks!
