Notes
Seems like a similar problem as T189636.
This error has attached to it, another error.
[{exception_id}] {exception_url} ErrorException from line 102 of /srv/mediawiki/php-1.34.0-wmf.4/extensions/Collection/templates/CollectionSuggestTemplate.php
PHP Warning: count(): Parameter must be an array or an object that implements Countable
This is a side-effect from the error being non-fatal. PHP assumes the null value for the unknown variable and continues, which then causes more problems. In this case, it means an array count operation is attempted on something that is not an array.
