sumo - Answered with error to command 0xa4: Get Vehicle Variable: unsupported variable 0x32 specified

Question

I'm trying to retrieve vehicle lateral speed using TraCI with a python script. However, I get the below error when I use the method:

C:Usersxxxsrcsumo-1.2.0est> python runner.py --nogui
Loading configuration... done.
Step #0.05Error: Answered with error to command 0xa4: Get Vehicle Variable: unsupported variable 0x32 specified
Traceback (most recent call last):
  .....
traci.exceptions.TraCIException: Get Vehicle Variable: unsupported variable 0x32 specified
Error: tcpip::Socket::recvAndCheck @ recv: peer shutdown
Quitting (on error).

This is my sumocfg file:

    </input>

    <time>
        <begin value="0"/>
        <end value="500"/>
        <step-length value="0.05"/>
        <lateral-resolution value="0.3"/>
    </time>
