Activating debug log for http binding on OH3

I found the instructions somewhere to bring the http binding into debug (and separate, of course out of) logging mode, using the console and OH3.

log:set DEBUG org.openhab.binding.http
log:set DEFAULT org.openhab.binding.http

But this does not show me any new information in the openhab-cli showlogs. But this would be the only way to debug my delock http switch and see if the url that the http binding constructs, is actually the one I want. It is not working, probably some stupid mistake, I would resolve using increased log level.

Many thanks for any help!

Try TRACE instead of DEBUG

Thank you so much.
