Answer 1

Must be a problem with the php version . I was on php8 and was facing the same issue but when once I change to php7.3 the error became warning. Since the major changes in php7.4 and greater that might be causing the error of count()

Answer 2

As of PHP 7.2, the count() function will throw a warning when a value passed into it is not countable. Later on, this was made to throw a fatal error in PHP 8.0
See https://www.php.net/manual/en/function.count.php
Changelog
Version
Description
PHP 7.2
count() will now yield a warning on invalid countable types passed to the value parameter.
Since PHP 8.0 is a relatively new (and major) release that just came out 4 months ago in November, there is a good chance that a very large portion of PHP libraries aren't up to date yet. (I'm still developing in PHP 7.4 because of this.)
Assuming you're using the google/apiclient package, you should be good to go now as it seems to have been updated to support PHP 8.0 on Jan 19th in v2.9.0 (almost a month after you asked this question).
Edit: This is all based on the assumption you're running PHP 8.0, as this is the only version of PHP that throws a fatal error when passing a non countable variable into count().
