Error while running multiple yaml files using Artillery pro

[JayasimhaNagaraj]

Hi Team,

We have procured Artillery pro license . However, when we are trying to trigger 2 parallel tests with different yaml files via Artillery pro using multiple command prompts, we are getting below error:

"Maximum number of concurrent test runs(1) has been reached.
Please wait for other tests to complete and try again"

Only 1 file amongst the 2 yaml files is working.

We are using below command:
artillery run-test -o <>.json --cluster ArtilleryPro --region eu-west-2 --count 1 --launch-type ecs:fargate <>.yml
