Could not update folder level actions from source<id> FATAL: "Failed to recompute children" when indexing multibranch pipeline

[Ashish Kumar]

Hi All,

I'm getting this following error which is happening for a particular gerrit repo. The configuration is working for all other repos in my project but not in this particular one.

The multibranch pipeline catalog template is

multibranch:

  branchSource:

    gerrit:

      remote: ${ProjectRepositoryUrl}

      credentialsId: ${GitHTTPSCredentials}

      traits:

        - $class: ChangeDiscoveryTrait

          queryString: ''

        - $class: RefSpecsSCMSourceTrait

          templates:

          - value: '+refs/heads/*:refs/remotes/@{remote}/*'

        - $class: SubmoduleOptionTrait

          extension:

            disableSubmodules: false

            recursiveSubmodules: true

            parentCredentials: true  

and pipeline config is 

pipeline {

    /**###################### Agents Config ######################**/

    agent {

        kubernetes {

            inheritFrom "${PodName}"

        }

    }

    options {

        // This will checkout the changed repository that has triggered this pipeline to a sperate folder named "tmp_repository", to be used later in the build

        checkoutToSubdirectory('tmp_repository')

        buildDiscarder(logRotator(numToKeepStr: 'unlimited'))

    }

    /**###################### Stages ######################**/

    stages {

        /**###################### Gerrit Review Log ######################**/

        stage('Init') {

            steps {

                script {

                    gerritReview message: "Build started: ${BUILD_URL}"

                }

            }

        }

        /**###################### Cloning Manifest Repository ######################**/

        stage('Cloning Manifest Repo') {

            steps { // Executes on JNLP, no specific container required

                script {

                    echo "Cloning the Manifest repository: ${ManifestRepoName}"

                    // This will checkout the manifest repository into a folder under the same name as the repository

                    dir("${ManifestRepoName}") {

                        checkout([

                        $class: 'GitSCM',

                        branches:

                        [[name: "*/${ManifestBranch}"]],

                        doGenerateSubmoduleConfigurations: false,

                        extensions: [[

                            $class: 'LocalBranch',

                            localBranch: '**'

                          ],[

                            $class: 'CleanBeforeCheckout',

                            deleteUntrackedNestedRepositories: false

                          ]],

                        submoduleCfg: [],

                        userRemoteConfigs: [[credentialsId: GitHTTPSCredentials, /*Netid credentials must be used instead of HTTPS tokens.*/

                                             url: ManifestRepoUrl]]

                        ])

                    }

                }

            }

        }

}

The multibranch indexing itself is not happening and it is unable to detect Gerrit branches/changes

Can someone assist on this

Sounds more like a problem on the gerrit side. Maybe check https://confluence.atlassian.com/fishkb/git-indexing-fails-due-to-bad-pack-header-371360062.html for one reason.

Ya it was an error from gerrit side. There was this particular change refs/changes/24/106224/4:refs/remotes/origin/24/106224/  in which a patchet we suspected it was not properly uploaded, possibly interupted in middle of a push. We abandoned the change since the owner was not available and then it worked fine.

The multibranch scan is happening successfully now in jenkins. The changes are getting picked up as usual.
