Debug mode fails to open alexaDiscovery.json

[dazzlee42]

Analysis

Hi, Just updated to v0.6.9 and I have debug turned on for the plugin. Restarted homebridge and after a few seconds it restarts. I managed to disable the plugin and check the logs. Seems it is now trying to save out to alexaDiscovery.json when in debug mode and failing.

Expected Behavior

Don't crash ;-) Save the file to a known location.

Steps To Reproduce

Enable debug, restart.

Note, turning off debug, bypasses the code trying to open the file, so I'm back and working. Not sure what debug was giving me, would be good to get this working with debug and have the json files to review. Thanks

That option is saving a copy of your configuration that was shared with Amazon alexa to aid in debugging a users setup. The file is written to the current directory from which homebridge was installed, and assumes that the directory is writable. Do you need debug enabled for something ?

[dazzlee42]

Hi, not specifically, but I normally run with debug on, just in case. Was this changed, as it was not crashing before. Shouldn't it save to the config directory, where all the other plugins save to? Cheers
