WP NEW PAGE creation now throws an exception

This thread is resolved. Here is a description of the problem and solution.

Problem:
When trying to create a new Page after deleting some post relationships, I see a Fatal Error and I cannot continue.

PHP Fatal error: Uncaught InvalidArgumentException: First argument is not a post. in /path/to/wp-content/plugins/types/vendor/toolset/toolset-common/inc/autoloaded/field/group.php:60

Purge all server-side caching and try again.

Ive been creating and deleting new post types, forms, views, taxonomies, etc.
Then deleting them all and starting from scratch.

I have ONE custom post type left w/ an associated custom field set.
I have ONE form associated with it, left as well.
Deleted everything else.

Not sure TOOLSET is doing proper cleanup when you delete stuff.

Now when I try to create any new WP page, it throws an exception.

Hi, I can see your site uses a Redis object caching system. Can you try purging the object cache and any other server-side caching systems? You may have to log into your server's control panel to do this. On another User's site, purging the cache recently solved a similar problem.

I already go it working, but you are likely very correct.

Once I bounced ALL caches - including redis, it started working again.
Ill keep this is in mind when I hit glitches in the future.
