wp litespeed-purge all returns 403

I’m trying to automatically purge the cache when new code is launched using wp litespeed-purge all but every time I get a 403 error. I suspect it’s a nonce issue, but I haven’t been able to confirm that. Below is the output when I add the --debug flag.

$ wp litespeed-purge all --debug
