Unable to run a simple experiment profile

Software
1

Hello, I’ve been trying to circulate alt media using the experiment profile, and even if it doesn’t raise any error, this does not work (the pumps don’t move, and the problem is not hardware). Could someone help me? I have the latest software version, and the YAML file syntax is correct based on the YAML validator

Hi @Yves_LM,

The error is being swallowed here, and not presented to the user. I’ll try to make this more clear. The problem is that circulate_alt_media expects a duration option:

        actions:
          - type: start
            t: 0s
            options:
              duration: 120

And you can drop the stop action too. In total:

Hi Cam,
Thanks a lot for your answer, it worked! I tried with a duration first, but I didn’t know the function wasn’t able to handle “120s” or “2m”, but only “120”.

the function wasn’t able to handle “120s” or “2m”, but only “120”.

that would be a nice change!
