I tried to get motion planning solutions from a docker submission provided by former competitioners, I got the solutions successfully but was not able to read them. The version of commonroad-io of the docker submission is 2022.1, I built a conda envirionment to read the results, I used the code example provided in commonroad-io gir repository to read them, I had no problem reading and visualizing the scenarios, but when reading the solutioins, the following error pops out:
Traceback (most recent call last):
