VS Code 和 AWS SAM 本地调用问题

Question

我在 VS Code 上有一个无服务器项目，安装了 Docker 桌面 4.10，但我不知道为什么上周五一切正常，因为周一我遇到了奇怪的错误，我无法弄清楚。我尝试更新 AWS CLI、Docker、VS 代码及其扩展，但没有任何进展。

这是我的 launch.json 文件：

{
    "configurations": [
                {
            "type": "aws-sam",
            "request": "direct-invoke",
            "name": "lambda:index.handler (python3.8)",
            "invokeTarget": {
                "target": "template",
                "templatePath": "${workspaceFolder}/sam-utilites/template.yaml",
                "logicalId": "Services2"
            },
            "sam": {
                "containerBuild": true
            },
            "aws": {
                "credentials": "profile:default"
            },
            "lambda": {
                "runtime": "python3.8",
                "payload": {
                    "path": "${workspaceFolder}/sam-utilites/events/update_item_name.json"
                },
                "environmentVariables": {
                    "TABLE_NAME": "Services2"
                }
            }
        }
    ]
}

我遇到了第一个错误：

Exception has occurred: ImportError       (note: full exception trace is shown but execution is paused at: <module>)
cannot import name 'winreg' from 'six.moves' (unknown location)
  File "\var\runtime\dateutil\tz\win.py", line 13, in <module> (Current frame)
    from six.moves import winreg
  File "\var\runtime\dateutil\tz\tz.py", line 29, in <module>
    from .win import tzwin, tzwinlocal
  File "\var\runtime\dateutil\tz\__init__.py", line 2, in <module>
    from .tz import *
  File "\var\runtime\botocore\compat.py", line 27, in <module>
    from dateutil.tz import tzlocal
  File "\var\runtime\botocore\configloader.py", line 19, in <module>
    from botocore.compat import six
  File "\var\runtime\botocore\session.py", line 29, in <module>
    import botocore.configloader
  File "\var\runtime\boto3\session.py", line 17, in <module>
    import botocore.session
  File "\var\runtime\boto3\__init__.py", line 16, in <module>
    from boto3.session import Session

我认为 Docker 映像或将层传递给 Docker 的模板文件有问题。 这是我的模板文件：

今晚遇到了这个问题。

看到这个：https://github.com/aws/aws-sam-cli/issues/3347

就我而言，我在断点中检查了“未捕获的用户异常”。清除它修复了我的调试器！
