Describe the current, buggy behavior

When running this cli command: wp theme update --all I get a ton of these notices:

Notice: Trying to access array offset on value of type null in phar://C:/OpenServer/modules/php/PHP_7.4/wp-cli.phar/vendor/wp-cli/extension-command/src/Theme_Command.php on line 472
Notice: Trying to access array offset on value of type null in phar://C:/OpenServer/modules/php/PHP_7.4/wp-cli.phar/vendor/wp-cli/extension-command/src/Theme_Command.php on line 473

There is a similar notice for wp plugin update --all, see https://github.com/wp-cli/wp-cli/issues/5422, and it was fixed (not released though).

I'm on WP 5.6, WP CLI 2.4.0, PHP 7.4.4.

[pdobrescu]

I had the same issue with WP 5.6, WP-CLI 2.4.0 and PHP 7.4.13

After updating to the latest nightly (with wp cli update --nightly) the warning is gone (horray!)

[slaFFik]

Nightly version breaks my building steps, so I can't use it.

[wojsmol]

@slaFFik Please describe what's broken.

[schlessera]

Yes, indeed, would also love to know what is breaking in current nightly.

[nlenkowski]

Its been awhile since this was reported, but I'm still seeing this issue as well.

I'm running WP 5.7, WP-CLI 2.4.0 and PHP 7.4.15. I haven't tried the nightly release of WP-CLI yet.

I should note that the warnings and notices seem to only be output when define( 'WP_DEBUG', true ); is set.

$ wp core update && wp plugin update --all && wp theme update --all

I see the same problem in WP-CLI 2.7.1 (php8.0)

WP_DEBUG true/false irrelevant.

Any work around available after 2 years perhaps..? :)

Happy to add troubleshooting if needed. Multiple sites involved.

Assuming this is fixed up now. Feel free to stop by the #cli channel on WordPress.org Slack if you'd like help debugging further.
