I just pulled the latest version of gateway bridge v4.0.10 but it is not passing any metadata into the uplink sent from the gateways. I had to drop it back to version 4.0.9 to get this information again.
The bridge also failed to pass data as json to debug as well iirc it was an rpc error.
v4.0.10 (missing meta)
v4.0.9 (with meta)
