Handlers running/executing twice on `sst dev`

I've noticed that any Lambda functions (APIs & Queue handlers) seem to execute twice when running them via sst dev.

Here's a Lambda API firing off twice from only a single call:

|  Build       FeedbackApi
|  Invoke      FeedbackApi
|  +8ms        Received feedback event {
|  +8ms          token: 'eyJhbGciOiJIUzI1NiJ9.eyJtZXNzYWdlSWQiOiIzY2E5N2JjOS00OWU4LTRmNGQtYjI2Yy0yYmUxY2MyOTg1YjUiLCJlbWFpbCI6ImFrc2hheXBldHRhQGdtYWlsLmN

|  +8ms          score: 'good'
|  +8ms        }
