Is your bug report directly related to a specific command?
wp cron event run --due-now
Are you unsure about what repository to post the bug report into?
Just head over to the wp-cli/wp-cli repository and create a new issue in that repository. The maintainers can still move the bug report into the correct repository later on.
--- ✅ If you are in the correct location now... --->
- Yes, I reviewed the contribution guidelines.
- Yes, more specifically, I reviewed the guidelines on how to write clear bug reports.
Describe the current, buggy behavior
PHP warnings when invoking that WP CLI core command (each time, also for subsequent times).
Describe how other contributors can replicate this bug
The warning is emitted when triggering the WordPress cron (roots.io Trellis with a Bedrock WordPress site; system cron job) and checking the output. It doesn't seem to cause other problems, but I don't like PHP warning messages in command output.
Describe what you would expect as the correct outcome
No PHP warnings when the WP CLI cron command is used.

Provide a possible solution
Probably just adding some check for a variable being set and an array in a foreach loop.
But maybe there is a deeper issue that should also be resolved?
Thanks for the report, @strarsis !
It seems like some of the underlying data was corrupt. Were you able to debug this further?
