FMI Toolbox Matlab Azure Devops CI Pipeline Bugs with network service account

Question

I'm making a CI pipeline for a Matlab/Simulink project on Azure DevOps. The build pipeline is stable and reproduce same output as local computer execution. The test pipeline however is bugging. Any solution is welcome!

Action:

My project uses Modelon FMI toolbox to run plant models. My local computer runs all matlab unit test, which run a Simulink file including my Modelon FMU, without any issue and generate a jUnit Test report xml. I called the same files to run using a azure-pipeline.yml file.

Expected:

I expected the same result as my local run with the same pass/fail result showed on the job run CLI.

Result:

At execution from Azure Pipeline those FMU plant cause a failure on all my test. it's the same error 29 times.

Info:

This is what I tried.

1. I verified I had the appropriate licenses:

Version of the Licensing toolkit client library
    v11.10.0.0 build 95001 x64_n6
---------------------
Performing test for feature: FMI_TOOLBOX
    Feature: 'FMI_TOOLBOX'

2. I changed the user account of the Azure Pipeline Agent Service that was running to my own account and all worked fine . It build & test all my FMU blocks like it did locally and then publish report on Azure Pipelines. I see the bug only happens on Azure default network service account. For security reasons and other reasons, I would also like it to work on network services.

3. I did some quick lecture online.

Answer 1

SOLUTION:

I found that Network Service Account and My User Account use different %APPDATA% folder.

C:\Users\*******\AppData\Roaming\Modelon\Licenses\Server

and

C:\Windows\ServiceProfiles\NetworkService\AppData\Roaming\Modelon\Licenses\Server

In the network service folder I had nothing, but in my folder I had a fmi_licence.lic file with this content:

SERVER **************.com ANY  *****
USE_SERVER

Upon adding the file to my Network service %APPDATA%, and adding these line to my Azure Pipeline YMAL File, the licence checked out to be a working network license and my project stopped working on DEMO mode when running on Network Service Account.
