Most property types(number, email, text, etc.) adds additional property input section when selected on action builder screen. But when select property is chosen, no additional property input is created on builder screen - thus, user can’t create update action.
After done some research, I suspect some part of update-action component code might be the culprit.
Code for update-action component* defines propertyTypes have ‘page’ parentType while it can have ‘database’ parentType. Maybe, because of this, ‘database-ish’ properties are not processed to create additional property input UI. I didn’t test other ‘database-ish’ properties like ‘multi select’, is also failing.
Hope this helps.
