The problem is that when I run a pipeline script with:

def projects = jiraGetProjects()
echo projects.data.toString()

I get code 200 with an empty list of project, instead of my 2 projects.

I have the following configuration:

Platform: Windows 10

Jenkins Version : 2.440.1

Jira Steps Plugin Version : 2.0.165.v8846cf59f3db

The strange thing is that on another PC, with configuration:

Platform: Windows 11

Jenkins Version: 2.426.3

Jira Steps Plugin Version : 2.0.165.v8846cf59f3db

Same pipeline script, I get code 200 but this time I get the correct list of projects.

I don't want to upgrade Jenkins because I'm afraid it will stop working. 

How can I fix this issue? What can be the cause? 

I'm authenticating on both PC with the same account in Credential mode and I stored the credentials with username and passworld on both PCs.
