Goal

I have a github organization job that runs a Jenkinsfile. I have modified the jenkinsfile to add a scheduled trigger as I want to trigger the pipeline every day for master branch now

Jenkinsfile

My jenkinsfile starts with following code :

// Schedule pipeline every morning on master
if (env.BRANCH_NAME.equals('master') ) {
    properties(
        [
            pipelineTriggers(
                [cron('''TZ=Europe/Paris
H 5 * * *''')
                ]
            )
        ]
    )
} 

Issue

But in my master job console I get following log => it is the opposite of what is expected.

My job is not scheduled

05:30:46 removeJobSchedule - Removed existing TimerTrigger with spec 'TZ=Europe/Paris 
05:30:46 H 5 * * *'

I do not understand what is going wrong.

Expected Behaviour

When creating a new job with same code , it works fine (github org AND multibranch pipeline) => is there something special if i modify an existing job ?

I would expect that the sub job master is scheduled correctly with given code
