I am trying to:
Update a custom field group with a new custom field and it causes a Fatal Error. I can create new custom field groups and create custom fields but I'm unable to add a new field after the initial save.

Link to a page where the issue can be seen:
This is on a development server and isn't publicly available.

I expected to see:
I expect the custom field group to save and accept my new field update.

Instead, I got:
This page isn't working

This is what I got via WordPress debug:
Fatal error: Uncaught InvalidArgumentException in /var/www/html/wp-content/plugins/types/vendor/toolset/toolset-common/inc/m2m/relationship/query/condition/type.php:28 Stack trace: #0 /var/www/html/wp-content/plugins/types/vendor/toolset/toolset-common/inc/m2m/relationship/query/condition_factory.php(90): Toolset_Relationship_Query_Condition_Type->__construct('', Object(Toolset_Relationship_Role_Parent)) #1 /var/www/html/wp-content/plugins/types/vendor/toolset/toolset-common/inc/m2m/relationship/query/relationship_query_v2.php(355): Toolset_Relationship_Query_Condition_Factory->has_type('', Object(Toolset_Relationship_Role_Parent)) #2 /var/www/html/wp-content/plugins/types/vendor/toolset/toolset-common/inc/m2m/relationship/query/relationship_query_v2.php(350): Toolset_Relationship_Query_V2->has_type('', Object(Toolset_Relationship_Role_Parent)) #3 /var/www/html/wp-content/plugins/types/application/models/post_type/relationships_settings/relationship_settings.php(240): Toolset_Relationship_Query_V2->has_type('') #4 /var/ww in /var/www/html/wp-content/plugins/types/vendor/toolset/toolset-common/inc/m2m/relationship/query/condition/type.php on line 28

It seems you have an RFG on those Custom Fields Groups, is this possible?
I tried several scenarios but could not replicate such an error.
I have however similar (and also not replicable yet) errors here:

https://toolset.com/forums/topic/php-fatal-error-uncaught-invalidargumentexception-on-custom-field-saving/

They may be related.

Can you maybe send me the exported Types and Fields from Toolset > Import/Export or a full copy of the site?

Also, it can help to test if without any other Plugin and a native theme this persists

Well - could you please tell me with custom field group you are having issue with?

Do your tests using 'Metadata for Search Engines' custom field group as it's the one that gives me the issue every time, but I have been able to recreate the issue with all field groups.

Well - we have a couple of more users reporting the same issue. I've passed your duplicator to our next level support for further debugging.

Please hold on for further updates, I'll get in touch with you as soon as I know more.

We just published Types new version 3.1.2.
=> https://toolset.com/download/toolset-types/#changelog

Could you please update your Types plugin and try to resolve your issue.
