调用 UpdateFunctionCode 操作 Lambda AWS 时发生错误 (MissingAuthenticationTokenException)

Question

I have a function in my Lambda named my-s3-function . I need to add this dependency to my Lambda Node.JS. I have followed this part to update the script with dependency included (though, I didn't follow the step wherein I need to zip the folder using zip -r function.zip. but instead I zip the folder by right-clicking it on my PC).

The zip file's structured like this inside:

|node_modules
    |<folders>
    |<folders>
    |<folders>
    ... // the list goes on
|index.js
|package_lock.json

Upon typing the code aws lambda update-function-code --function-name my-s3-function --zip-file fileb://function.zip to the terminal, I get the following response:

An error occurred (MissingAuthenticationTokenException) when calling the UpdateFunctionCode operation: Missing Authentication Token

What should I do to resolve this?

Based on the comments, this got resolved by configuring the credentials as described in the documentation.

Try first with exporting the credentials as described Environment variables to configure the AWS CLI . Once you are sure your credentials are correct then you can follow this Configuration and credential file
