Error installing 'hello-serverless' app: AWS Lambda deployment type not configured

[guneshsji]

Deploying "hello-serverless" Golang app on AWS lambda succeeds.
But installation to MM server fails with below error

DEBUG	appsctl/mattermost.go:36	updated local manifest	{"app_id": "hello-serverless", "deploy_type": "AWS Lambda"}
Error: failed to install the app to Mattermost: deployment type "AWS Lambda" is not configured on this Mattermost server

Manifest file content:

{
	"app_id": "hello-serverless",
	"version": "v1.2.0",
	"display_name": "Hello, Serverless!",
	"homepage_url": "https://github.com/mattermost/mattermost-app-examples/golang/serverless",
	"requested_permissions": [
		"act_as_bot"
	],
	"requested_locations": [
		"/command"
	],
	"aws_lambda": {
		"functions": [
			{
				"path": "/",
				"name": "hello-serverless",
				"handler": "hello-serverless",
				"runtime": "go1.x"
			}
		]
	}
}

What could be a potential issue here.

@hanzei Hi, do you know what could be the issue,
If I want to build an integration with twilio, what should I opt for, plugin or app ?

@guneshsji Did you setup the AWS env variables as described in https://developers.mattermost.com/integrate/apps/deploy/deploy-aws/#set-aws_deploy_-environment-variables?
