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，我不知道为什么上周五一切正常，因为周一我得到了奇怪的错误，我无法弄清楚。我尝试更新AWS CLI, Docker, VS code及其扩展，但没有进展。

这是我。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"
}
}
}
]
}

我得到了第一个错误:

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 "varruntimedateutiltzwin.py", line 13, in <module> (Current frame)
from six.moves import winreg
File "varruntimedateutiltztz.py", line 29, in <module>
from .win import tzwin, tzwinlocal
File "varruntimedateutiltz__init__.py", line 2, in <module>
from .tz import *
File "varruntimebotocorecompat.py", line 27, in <module>
from dateutil.tz import tzlocal
File "varruntimebotocoreconfigloader.py", line 19, in <module>
from botocore.compat import six
File "varruntimebotocoresession.py", line 29, in <module>
import botocore.configloader
File "varruntimeboto3session.py", line 17, in <module>
import botocore.session
File "varruntimeboto3__init__.py", line 16, in <module>
from boto3.session import Session

我认为Docker图像中有问题，或者在将层传递给Docker的模板文件中有问题。这是我的模板文件:

今晚遇到这个问题。

参见:https://github.com/aws/aws-sam-cli/issues/3347

在我的例子中，我检查了"未捕获的用户异常";在断点中。清除它修复了我的调试器!
