Description
I want to use the latest isaac-ros-visual-slam version of isaac 3.2 to achieve localize in an exist map. I send localization service by visual_slam/localize_in_map to localize current stereo image and start, using the same ros2bag. But it always failed and return message "CUVSLAM_LocalizeInExistDb Error 2". I check it in cuvslam.h and find 2 refer to "CUVSLAM_INVALID_ARG".
I want to know how to solve it ?

Research direction
Start by reproducing the visual_slam/localize_in_map service call with the same ros2bag, Isaac 3.2, and the reported isaac-ros-visual-slam version. Inspect cuvslam.h to confirm the CUVSLAM_INVALID_ARG meaning and identify which argument is rejected; done means the current stereo image localizes in the existing map without Error 2.
