Hi @ngocngoan thanks for reporting, it's an experimental feature and is still being worked on, but we can leave this open until it's working for everyone.

Found same. Pity! I'll be patient J

Is there a requirement for system architecture? We also get this error and can't use debugger.

[ZhenxingXiao]

is it possible if we can fix and start the debugger server locally? just want to analysis my codes. or is there any documents about that, so I may can figure out some solutions by myself. thanks.

Debugging is not yet fully released as part of the SDK, but is coming very soon! @walter-erquinigo

This will be fixed in the upcoming release on Linux, and Mac will be supported in the following release.

Thanks for the report!
