There was an error.

Invalid Message - The message could not be parsed.


How I troubleshot this:




  1. Rolled by my policy to the original data → same issue

  2. Went to https://jss/changeManagementLogs.html to replay my changes



I then clicked on 'details' and noticed this:



Distribution Point ID -1


I then deducted it's because I don't have any Distribution point configured.



For the story, here's why:
- my JSS was destroyed by the ops team by mistake (it’s a sandbox, no worries)
- I setup a new one with same address and credential
- overnight, AutoPkg pushed his package on the distribution point and the JSS
- but I didn’t configure the distribution point on the JSS (hence the code "Distribution Point ID -1")
- now that I have setup the distribution point again, it works



Key takeaway is: Use https://jss/changeManagementLogs.html

@ftiff -1 is correct as per this.



It means the JSS allocates a DP, but with no DP in the JSS... Yep that'll not work.


@bentoms you're the man


We had this error as well. Turns out the MacBook Air didn't have a Serial Number set. A quick session with AST and we're good to go.


Ive seen this in our envrionment running 9.81. I have many distribution points but I can't undertsand why this is coming up. Also on this particular Mac, there are several cached packages that do not list on the JSS inventory. It just shows 5 cached packages.


Getting the same Invalid Message - The message could not be parsed error here as well. I'm a Jamf Cloud customer with a Cloud Distribution Point (setup as master) and no File Distribution Point configured, so a bit different from @ftiff's original issue. When verifying the details at https://jss/changeManagementLogs.html, the Distribution Point ID value was set to -1. I assume this is the case due to the Cloud Distribution Point. Is anyone able to provide some insight here?
