Add population upon founding patheon and religion

[Cagarustus]

I want to make it so that every city adds +1 population when founding a pantheon, and a further +2 population when founding a religion.

I've coded the following, but it doesn't appear to be working:

INSERT INTO Modifiers (ModifierId, ModifierType, SubjectRequirementSetId)
VALUES
('CAG_TRAIT_INDIA_GREATAGAIN_1', 'MODIFIER_PLAYER_CITIES_ADD_POPULATION', 'PLAYER_HAS_PANTHEON_REQUIREMENTS'),
('CAG_TRAIT_INDIA_GREATAGAIN_2', 'MODIFIER_PLAYER_CITIES_ADD_POPULATION', 'PLAYER_FOUNDED_RELIGION_REQUIREMENTS');

INSERT INTO ModifierArguments (ModifierId, Name, Value)
VALUES
('CAG_TRAIT_INDIA_GREATAGAIN_1', 'Amount', '1'),
('CAG_TRAIT_INDIA_GREATAGAIN_2', 'Amount', '2');

INSERT INTO TraitModifiers (TraitType, ModifierId)
VALUES
('TRAIT_CIVILIZATION_DHARMA', 'CAG_TRAIT_INDIA_GREATAGAIN_1'),
('TRAIT_CIVILIZATION_DHARMA', 'CAG_TRAIT_INDIA_GREATAGAIN_2');
-------------
In my mind, there must be something wrong with the SubjectRequirementSetId, but I'm not sure. The Database Log doesn't indicate anything, so I'm not sure what's wrong.
