Error when running make sanity-test: TabError in e2_single_agent example

High Level Description

Hi there! I encountered an issue when running make sanity-test, and below is the full error output I see in the terminal: (.venv) ubuntu@ubuntu-Legion-Y9000P-IAH7H:~/SMARTS$ make sanity-test scl scenario build --clean scenarios/sumo/loop Building: scenarios/sumo/loop scl scenario build --clean scenarios/sumo/zoo_intersection Building: scenarios/sumo/zoo_intersection PYTHONPATH=/home/ubuntu/SMARTS PYTHONHASHSEED=42 pytest -v

Version

System Information:

OS: Ubuntu 22.04

Python Version: 3.10.12

SMARTS Version: Latest clone from the GitHub repository

Additional Information:

The error happens around line 23 in examples/e2_single_agent.py.

When running make sanity-test, all other tests pass, except for the e2_single_agent test.

Could anyone please help me resolve this? Is there a known solution to this indentation error, or am I missing something important?
