cannot import name 'realsense_msgs__msg__StreamInfo' in record.py

I am trying to use the record example from gen2-record-replay, and am getting an error: ImportError: cannot import name 'realsense_msgsmsgStreamInfo' from 'rosbags.typesys.types' . I am trying to record depth and colour streams for later playback using this command: python record.py -save color depth --fps 10

I have also tried installing depthai 2.17.0.0, as in the requirements. The installation failed in building the wheels, but I have managed to get it installed with python 3.8. Unfortunately, this throws different errors:

@afgoo could you first do pip install rosbags?

[afgoo]

@Erol444 Thanks - I have already installed rosbags with pip on both python 3.8 and 3.11.

[Erol444]

@afgoo is it version rosbags==0.9.11?

[afgoo]

No, pip install rosbags installed version 0.10.3 in python 3.11 and 0.9.23 in python 3.8. I'll try 0.9.11.

[afgoo]

rosbags v0.9.11 works with python 3.8 and depthai 2.17.0.0.

However, I am still having issues with the recorder. It is able to record the 'color' stream, and/or the 'left' stream. It fails when recording the 'right' stream, or the 'depth' stream. The right stream creates the calib.json, but no data file, and the 'depth' stream creates a very small (~5 kB) .bag file, which seems to have no data.
