I recently got the nRF52840DK and have been able to build/flash a couple simple samples. However when attempting to try the OpenThread CLI example on tool chain v1.6.1 and v1.7.0 there seems to be an issue generating the "compile_commands.json". After poking around I was unable to determine why this is happening and tried deleting and recreating the sample a couple times. Tweaking the build config gave the same result seen below. Did I miss something in the documentation on running thread examples?
