Error message at startup in the debug console?

After having had issues with the debugger I have noticed some strange messages in the debug console, 1. and 2. line (see below in bold) after the debug console starts sending output.

What does it mean and is it a real problem? The debug session seems to start and work okay?

I also see these errors in the Debug Console. Not sure what the consequence is.

I have seen this dozens of times yet no negative consequences for that.

Since it also happens on the CLI (pio debug ...) you can open an issue at Issues · platformio/platformio-core · GitHub.
