[Vuejs]-How to fix error " [vuex] expects string as the type, but found object" on Firebase err promise

The problem is this line:

dispatch(newPayload);

Dispatch should be passed two arguments. The first is a string referencing the action name, the second should be the payload.

e.g.

dispatch('actionName', newPayload);

I don’t know what action you’re trying to call so I can’t be more specific.
