Current Behavior

I am calling an action, and the action has ctx.meta available. as I set it during authorize phase. In hooks -> after, I change some response based on condition and emit an event. Emitting event has all data but missing meta. When I access ctx.meta, it is empty.

Expected Behavior

It should have ctx.meta available.

I am seeing this issue as well. How do I inject meta into an event?

[ujwal-setlur]

Ok, I figured it out. If you specify a meta key in the options object, the ctx.meta is then populated:

await serviceBroker.emit(
    'eventName',
    { foo: 'bar' },
    {
      meta: {
        auth: {}
      }
    }
  );
