GAS ability doesn't trigger by gameplay Event if the ability has a AsssetTag

As the title says, I’m activating an ability by event, to make things much clear as possible:

I have a Dash ability, which at the “onEndAbility” sends a gameplay event to the avatar actor, the second ability has like trigger “onGameplayEvent” the tag that the dash ability sends.

This works fine, till I don’t add an assetTag to the second ability, in which case, the ability won’t trigger at all.

Am I missing something?
