无法使用SLS在本地调用AWS Lambda [英] Unable to invoke aws lambda locally using sls

问题描述

我正在使用sls框架来启动我的代码，直到今天，它仍能正常工作.未修改serverless.yml的配置，并且我尝试重新安装sls，但似乎无济于事.

Im using sls framework to launch my code and it was working fine until today. serverless.yml's configuration wasnt modified and ive tried reinstalling sls but nothing seems to work.

在抛出以下命令后，我的所有存储库都会出现以下消息: sls调用本地-f function_name --accountId $ accountId

The following message occurs for all my repos after throwing the following command: sls invoke local -f function_name --accountId $accountId

错误消息:

推荐答案

我发现了问题所在.调用正在运行时发出警告:

I figured out what's wrong. There was a warning while the invocation was running:

 Serverless Warning --------------------------------------
  A valid environment variable to satisfy the declaration 'env:MY_API_KEY' could not be found.

因为这是一个警告，所以我只是忽略了它，它以前也起作用，但是显然框架现在不喜欢它.通过删除变量或定义变量来处理警告可以解决我的问题.

Since it was a warning I just ignored it and it previously worked but apparently the framework doesnt like it now. Dealing with the warning either by removing the variable or defining it resolved my issue.
