Jenkins java.lang.NullPointerException:无法调用方法

有下一个领域，我试图在我的工作结果发送松弛

        }  finally {
            sh(script: 'ls -lah')
            slack.jobResultNotification(currentBuild.result, '#some_channel',null,null,null,'https://hooks.slack.com/services/XXXXXX/XXXXXX/XXXXXXX')
        }
    }

但每次我

java.lang.NullPointerException: Cannot invoke method getSecret() on null object

用于松弛通知的函数（我只添加了代码的重要部分）

为了信誉

def getCredentialsById(String credsId, String credsType = 'any') {
    def credClasses = [ // ordered by class name
                        sshKey    : com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey.class,
                        cert      : com.cloudbees.plugins.credentials.common.CertificateCredentials.class,
                        password  : com.cloudbees.plugins.credentials.common.StandardUsernamePasswordCredentials.class,
                        any       : com.cloudbees.plugins.credentials.impl.BaseStandardCredentials.class,
                        dockerCert: org.jenkinsci.plugins.docker.commons.credentials.DockerServerCredentials.class,
                        file      : org.jenkinsci.plugins.plaincredentials.FileCredentials.class,
                        string    : org.jenkinsci.plugins.plaincredentials.StringCredentials.class,
    ]
    return com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(
        credClasses[credsType],
        jenkins.model.Jenkins.instance
    ).findAll { cred -> cred.id == credsId }[0]
}

您是否有ID为

当查看您的.jenkins.url/凭证时？是的！我试图使用slack integration id。我得到了相同的id。您有id为

当查看您的.jenkins.url/凭证时？是的！我试着使用slack集成id。我得到了同样的结果。
