Error: Invoked function failed - Cannot find module 'uuid/v4'

I have received an Error: Invoked function failed with the message Cannot find module 'uuid/v4':

{
    "errorType": "Runtime.ImportModuleError",
    "errorMessage": "Error: Cannot find module 'uuid/v4'",
    "trace": [

    ]
} 

I have the same issue reported here https://stackoverflow.com/questions/57906632/lambda-code-works-on-node-v8-10-but-not-nodejs-v10-x , it seems that with nodejs v10 I should add the library. I have solved creating an AWS Lambda layer with the library and adding reference in serverless.jml

Use of the Commands field in Parameters?

For the life of me, I've searched and searched and can't find a reference to what "command" actually does in the parameters sub-section. Is it another way to comment the section? TIA.

SAM launch configuration for Flag function does not pass payload to lambda

This is not an issue with code. I would like to learn why SAM is not passing payload to lambda. I have added launch configurations for both SubmitApplicationFunction and FlagApplicationFunction in Cloud9 as shown below.

Running SubmitApplicationFunction launch configuration works as expected passing the payload to lambda, however running FlagApplicationFunction launch configuration does not pass payload to lambda.

Both functions work when running with aws lambda invoke

Any ideas on what I may be doing wrong here?
Thanks.

Invalid base64 error when executing with AWS CLI v2

Need to add --cli-binary-format raw-in-base64-out if you're using AWS CLI v2.

https://step-functions-workshop.go-aws.com/30_setting_up_our_services/30_exploring_account_app_service.html

Should be

aws lambda invoke --function-name sfn-workshop-SubmitApplication --payload '{ "name": "Spock", "address": "123 Enterprise Street" }' --cli-binary-format raw-in-base64-out /dev/stdout

Kudos for an outstanding tutorial

I can't seem to message you on Twitter so l wanted to send my tremendous thanks and appreciation.

ApiGateway Integration

Here's the first my first attempt to add api gateway integration to the workshop example. It is working but may need some cleaning up. Suggestions are welcome.

Clipboard and click to view diff instructions

Can you provide instructions on how to achieve the clipboard and click to view diff effect with new files/updates to existing files?

Adding a new file and updating the paths in code such as this
with ___CLIPBOARD_BUTTON code/variants/template.yml/0-initial__template.yaml&code/variants/template.yml/1-fixing-permissions__template.yaml|

results in file exists on disk but not on HEAD error from Hugo during the build.

Specifically, I would like to

• Add a new yaml file under code/variants
• Put the contents of the new file in the clipboard (using the this content button)
• Show the new file diff using the Click to view diff button (similar to Home > Our first orchestration > Fixing Permissions > Make these changes > Step 4 )
• Make further changes to the template.yaml and use clipboard/diff feature to highlight those changes.

Thanks.
