The ingestor silently fails when the handler configuration is wrong

By mistake in some experiment I specified the wrong [entrypoint for the ingestor handler](https://github.com/developmentseed/eoapi-cdk/blob/239b0a9b19090a7da7d8790cd23cc70257431f03/lib/ingestor-api/index.ts#L163). I was expecting that calls to the [API handler](https://github.com/developmentseed/eoapi-cdk/blob/239b0a9b19090a7da7d8790cd23cc70257431f03/lib/ingestor-api/index.ts#L49) to return an error. It is not the case, whereas if I look at the logs of the ingestor lambda itself, I do see the expected error. Somewhere along the way the error is silenced.
