Merging multiple scans into a single structure

I am currently working on a project involving the merging of multiple scans into a single structure using Room plan json file. I am facing an issue and would greatly appreciate your assistance in resolving it.

The problem I am encountering is as follows: "Cannot process multiFloorPlan: Invalid room location in structure"

Captured room json file paths:

We are using same code as in example.
