Comment (by NextScripts):

 Please see my example above. I am passing clear integer values 1 and 2 as
 parameters. Getting error. Integer is "countable", right?


 Replying to [comment:8 adamsilverstein]:
 > I'm not sure this is a WordPress bug, it looks like this is happening
 when plugins/themes are mistakenly passing a non-countable 7th variable.
 The `add_submenu_page` function did not support the 7th variable until we
 added it for `position` (as an int) in WordPress 5.3. Passing anything
 there was unexpected and unsupported.

 `_doing_it_wrong` and use the default priority? What do you think
 @welcher?
