My only issue was that the execution of an inngest function wasn't completely intuitive, at least in TS, and you have to think in terms of inngest or, more precisely, the abstraction it is providing. Is it an actor, a step function, an event consumer, a saga? or a combination of some?
When you get used to it it's nice, less overhead than building your own actor model or your own event sources, and really good visibility into what is happening.
