Tesla Fleet Integration - Commands not working?

HA Version: 2025.3.1

Guide Followed: Tesla Fleet - Home Assistant


I followed all the steps in this guide successfully and I am hosting my public key on my private domain publicly accessible.

Home Assistant runs locally (http://192.***:8123/).

The sensor data is shown in HA but trying to send commands I get the error:

Failed to perform the action button/press. 'Session' object has no attribute 'epoch'
