Policy is forever stuck at Pending state

What does the policy do? Does it cause a reboot of the machine or cause the Mac to otherwise disconnect from the network? Because policy logs in Jamf Pro only get updated when the policy running locally on the Mac has an opportunity to upload said log back to Jamf Pro. If for any reason your policy is causing the Mac to have it's connection to Jamf Pro interrupted before that upload can happen, it ends up staying in a "Pending" state indefinitely.

@mm2270, The policy will deploy the package to the mac machine. Please do let me know what is the issue and if you need any additional information

Did you create the package yourself?

I would suggest using the Check in trigger instead of all those other triggers. In particular, the startup trigger almost never works unless the machine is hardwired to the network and doesn't use any kind of certificate based connectivity. I see you're testing it against what looks like an Mac mini, so perhaps it is hardwired, but I don't know.
Login/Logout triggers should work, but again, it kind of depends on what kind of network connection we're talking about. The enrollment trigger is only going to run once, when it's enrolled, just as the name implies.

The recurring check-in trigger is the one that will run at a set interval, typically every 5, 15 or 30 minutes (plus some random delay added on)
I can't tell from your screenshots what frequency you have set. Is it once per computer or something else?

Thanks @mm2270, after checking the recurring check-in trigger the policy started executing.
