Are you triggering cron from the CLI?
Why would I be using CLI for it? The plugin was working fine until last WordPress update. After that 3 other plugins also started giving problems as well and two of the developers have already replied it will be fixed in their next update and one gave me a work around until they fix it.
I can’t duplicate and I haven’t had any other reports yet, when and where are you getting these notices?
They were sent from cron email, but I have removed the plugin completely for now, until I can figure out what the issue is.
Do you have DISABLE_WP_CRON defined true and are using an external wp-cron trigger? If so, that might explain why REQUEST_METHOD (and others) is not set, depending on the method that you’re using to trigger cron. Just a thought…
