hi there, I'm trying to set up a sensor to kick of a job after the previous execution of it ends, but i get a weird error, without too much detail to get to the bottom of it. I've tested running the job manually and it runs successfully and the sensor gets kicked off, however it fails with the error below:

Hi Jesse - what version of dagster is this? I think your sensor function needs to take a single argument even if it isnt used, but I believe we fixed that in a recent dagster version

Got it - addin an unused arg to your function (or upgrading) should fix this

Great upgrading to 1.2.4 did the trick! Thanks for the tip!
