I'm using MATLAB R2022a, and trying to read my .db3 file by ros2bag function.

When I run the function, it returned the error message 'Cannot dereference iterator at end of result set!' and failed.

What should I do to run ros2bag successfully?

When you use ros2bag function to rosbag files which .yaml file register more than two .db3 files, the function will fail and return the message.

Please record the data into individual bag folders such that they have their own "metadata.yaml".
