Describe the bug

I have the same problem as described in renovatebot/renovate#14409 (reply in thread)
When using binarySource=install with npm/node versions specified as engines in package.json and BUILDPACK=true set (cf. renovatebot/renovate#14409 (reply in thread)) I get the following error

DEBUG: Using node constraint "16.14.0" from package.json (repository=MY_REPO, branch=renovate/react-select-5.x)

       }

I assumed this was mitigated/solved by #346 but it doesn't seem so. Any ideas?

How do you start the docker container?

[florianklumb]

Here is an excerpt from the Jenkinsfile:

pipeline {
    agent {
        docker {
            label buildAgents.DOCKER_AVAILABLE
            image 'renovate/renovate:32.32.5'
            args '-v /var/run/docker.sock:/var/run/docker.sock -v /tmp:/tmp'
        }
    }

    environment {
        CONFIGURATION = 'Release'
        TZ = 'Europe/Berlin'
        ENV = '/usr/local/etc/env'
        RENOVATE_TOKEN = credentials('...')
        RENOVATE_DOCKER_USER = 'root'
        GITHUB_COM_TOKEN = credentials('...')
        RENOVATE_BINARY_SOURCE = 'install'
        BUILDPACK = true
    }

    parameters {
        string defaultValue: '', description: '', name: 'RENOVATE_ARGS', trim: true
    }

    stages {
        stage('init') {
            steps {
                sh 'renovate --version'
                sh 'rm -f renovate.log'
            }
        }

        stage('renovate') {
            steps {
                sh 'renovate --log-file renovate.log --log-file-level debug ${params.RENOVATE_ARGS}'
            }
        }
    }
}

@florianklumb why did you closed the issue?

[florianklumb]

Sorry for the mixup. I thought I should've opened a discussion instead but you guys were too fast to reply :-)
