Getting the error "Enter valid workload name", even after defining the $WORKLOAD variable

Hi, I am getting the below error, even after defining the $WORKLOAD variable. Any suggestions on how to fix this please?

[root@vm1 benchmark-runner]# python benchmark_runner/main/main.py 
  File "benchmark_runner/main/main.py", line 47
    logger.info(f'Enter valid workload name {environment_variables.workloads_list}')
                                                                                  ^
SyntaxError: invalid syntax
