Does your rosbag have the full TF tree? That's message filters saying that it didn't call the callback with the sensor data because there wasn't a tranform available when it queued. The queue expires old messages that weren't able to be transformed.

I suppose it could also be the case that you're on such a low compute platform that you're not able to process the SLAM system in time before things are being thrown out, but given you lack any map at all in your screen shot, I think its more likely that you're missing a complete TF tree. And I think if you were on an RPi or something very small, you would have mentioned that in the question ;-)

Edit: from your screen shot, you don't have the odom -> base link transform, that could be what's causing it, easily.
