AWS ElasticBeanstalk部署引发错误，“执行命令[app-deploy]-[PostBuildEbExtension]期间发生错误”

Question

我正在尝试将Laravel应用程序部署到ElasticBeanstalk环境中。我正在使用“ eb deploy”命令进行部署。命令运行正常。我已经成功地部署了我的应用程序。有时，我更新了CloudFormation模板以更改ElasticBeanstalk的环境名称。

然后，我还如下更新了.elasticbeanstalk / config.yml文件。

branch-defaults:
  master:
    environment: PatheinDirectoryTesting
    group_suffix: null
environment-defaults:
  MyanEat-test-env:
    branch: null
    repository: null
global:
  application_name: PatheinDirectoryApplication
  default_ec2_keyname: null
  default_platform: arn:aws:elasticbeanstalk:eu-west-1::platform/64bit Amazon Linux
    2 v3.1.0 running PHP 7.3
  default_region: eu-west-1
  include_git_submodules: true
  instance_profile: null
  platform_name: null
  platform_version: null
  profile: null
  sc: git
  workspace_type: Application

然后在终端中，我更新了“ eb”命令，以使用运行以下命令的正确环境。

eb use PatheinDirectoryTesting

然后我运行“ eb deploy”来部署我的应用程序。它成功部署了zip文件。然后，在上传zip文件后就抛出了错误。

然后我运行“ eb日志”以获取日志中的错误。这是我在日志中发现的错误。

我尝试删除CloudFormation模板并再次部署。然后，我部署该应用程序。错误仍然存​​在。我该如何解决？
