Plugin seems to be broken

[ajgraves]

Hello, on version 1.7.49.5 of grav, the update-notifications seems broken and unable to run. Attempting to run bin/grav scheduler -r update-notifications yields the following error output (full path sanitized):

PHP Fatal error:  Uncaught TypeError: Grav\Common\Data\Data::merge(): Argument #1 ($data) must be of type array, Grav\Common\Data\Data given, called in /src/Grav/Common/Plugins.php on line 273 and defined in /system/src/Grav/Common/Data/Data.php:203

Hi @ajgraves,

I couldn't reproduce this on a fresh install of Grav 1.7.49.5. Given the source of the error, I'm wondering if this is a site you recently upgraded to Grav 1.7, and/or if you have some other plugins installed with non-conventional YAML formatting in their configs?

[ajgraves]

Thanks for the reply!

The site has been running for a few months. This plugin has been installed pretty much the entire time, and according to the scheduler logs has never run successfully (I only discovered this while trying to figure out why backups were not being purged as expected). Let me play around some more after disabling other plugins to see if I can figure out any conflicts.

I haven't been able to work with disabling other plugins yet, however I can show you the scheduler output:

bin/grav scheduler -d
