You can start Lens application on debug mode from the command line to see more verbose logs. To start application on debug mode, please provide DEBUG=true environment variable and before starting the application, for example: DEBUG=TRUE /Applications/Lens.app/Contents/MacOS/Lens.
This is a great way to share FAQs!
Is there any way to control the logging level, or the location of the logs?
My Lens Desktop (Windows) seems to start in Debug mode despite not running from the command line.
You can set DEBUG=false to the shell. However this is the default for Lens.
