Jenkins Copy Artifact: "Unable to find project for artifact copy" when job is triggered by timer

Question

I have few multibranch projects on my jenkins:

MultiBranchA

• master_branch
• feature_branch1
• feature branch2... etc

FolderB

• MultiBranchB

  1. master_branch

• MultiBranchC

  1. master_branch

Branches from Project A triggers build in one of multibranch pipelines in FolderB

stage("tests") {
    when {
        { return params.FunctionalTests }
    }
    steps {
       catchError(buildResult:"SUCCESS", stageResult: "FAILURE"){
           script {
               if (params.FunctionalTests && params.OtherParam)
               build wait: true, propagate: true, job: 'FolderB/MultiBranchA/master_branch', 
               parameters: [string(name: 'passTreshold', value: '100'), 
                            string(name: 'unstableTreshold', value: '90'), 
                            other params....]
             }
         }
    }
}

Triggered build (ProjectB) copy artifacts from upstream project

stage ("Copy artifacts") {

    steps {
        script {
            echo "Try to copy artifacts"    
            copyArtifacts (projectName:"MultiBranchA/master_branch, filter: "image_file.swu", 
                           selector: lastSuccessful(), fingerprintArtifacts: true)
        }
   }
}

And everything worked fine until we added time trigger to ProjectA

triggers {
  cron( env.BRANCH_NAME.equals('master_branch') ? '0 2 * * *' : '')
}

Now when timer triggers build in ProjectA and it triggers job in ProjectB, coppyArtifact command fails with:

It fails only for jobs triggered by timer. I found information, that in this case copyArtifact plugin works with anonymous user permissions. We are using Role-based Authorization Strategy plugin and we don't want add read permissions for anonymous users.

I tried to add permissions to copy artifact in jenkinsfile of ProjectB (every possible option), didn't help

options {
    disableConcurrentBuilds()
    timestamps()
    buildDiscarder(logRotator(numToKeepStr:"10"))
    //copyArtifactPermission('MultiBranchA')
    //copyArtifactPermission('MultiBranchA/*')
    //copyArtifactPermission('MultiBranchA/master_branch')
    //copyArtifactPermission('*')
}

I also installed Authorize Project plugin but looks like it is not working well with multibranch pipelines, authorization side bar menu didn't show up. In "Manage Jenkins" > "Configure Global Security" > Access control for builds I added "Pre-project configurable build Authorization" and tried every possible option (run as system, run as specific user etc.), also didn't help. Any idea how to solve this?
