lagou

I'm developper of a private custom extension usable in Azure Devops.

I have a problematic around the output of task.json in our extension and wonder if you can help to clarify / resolve the problematic.

1-What works.

I have created a release with 2 step : First step, execute my extension Second Step, retrieve output variable (sorry for the naming of the task, I'm in testing mode)

Our task.json execute a script named vm.ps1

In this vm.ps1 script, I have a piece of code to set the value of the variable $VirtualMachineId:

This value is then retrieve with the second step of the release, azure powershell inline script :

The result is diplayed in the log :

My value is retrieved, the goal is accomplish.

2-What doesn’t work : Implement in the task.json

Now, if I want to fully implement this variable in the product, I need to add this one in the output section of our task.json :

So, the UI of our interface will be display in the output section like the example below ( do not be disturb to not see VirtualMachineId in the below image, it is an illustration image):

I run another time my release, as I can see in the log of the extension execution, the variable is set with appropriate value.

Then the Azure inline script execute and the value is empty :

To resume: If I declare the variable in the output section of the task json, I can't retrieve the value or the value is empty. Does anybody here have an idea of what I do wrong ?

Thanks to have take time to read me.
