Unable to export trajectory

[ShrutheeshIR]

This repository is fantastic. I am using a realsense D435i for VI SLAM. I collected some data, and ran rovioli on it, and it seems to work fine. I have attached an image of the trajectory marker.

However, when I try to export the trajectory onto a CSV file, I get the following error:
Check failed: it != channels.end() Channelgroup does not contain channel VISUAL_KEYPOINT_SCALES. I checked that I am using an inertial sensor, and thus, the keypoint scales should be obtained. How do I merely export the obtained trajectory?

I tried doing this both before and after rtl followed by optvi, and lc, which seemed to run fine.

I have followed the checklist, and there seem to be no problems with installation and running maplab.

Thanks
