No message, only "S3 object read"-log line

[FluidSense]

Hey! 👋

This library seems perfect for our use case, but I am currently struggling a bit on using it.

After following the setup, we do not receive any large message. Small messages are handled as they should normally, but when an S3-payload is received, all that happens is that a log line with "S3 object read, Bucket name: [...], Object key: [...]" is printed. No message is ever in the returned messages from .getMessages()

Is there an obvious mistake that I might have made?
