[golang/hello-world] Panic during sending a message

I'm following the guide,
but when I try to send any message I get the error in UI upstream call failed: failed to invoke via HTTP: Post "http://mattermost-apps-golang-hello-world:4000/send": EOF
and panic in logs:

golang/webhooks example error: info endpoint does nothing when sent to, app does not report messages to channel.

Manifest error running example

Repro steps:

Follow the instructions on https://developers.mattermost.com/integrate/apps/quickstart/quick-start-ts/
Error: "manifest has no deployment information (http, aws_lambda, open_faas, etc.)"

Expected:

App installs correctly

This error occurs for both the Typescript and Python examples.

The cause is there is a missing "http" node in the manifest.

Configure the dev environment and examples to work on Gitpod

@mickmister Maybe you have some ideas for this one?

Icon not found when trying to installl the hello-world app

Rework golang/oauth2 example to be exposed to the public web

Could be via something like ngrok.

Add TypeScript dynamic form example

From mattermost/mattermost-developer-documentation#919 via https://mattermost.atlassian.net/browse/MM-36974.

golang/lifecycle example error: Go error when trying to install and use lifecycle bindings.

Import v8 with go

The go example uses v6, and I'm trying to update my go program which uses github.com/mattermost/mattermost-server similarly.

Could you update the example on how to use the latest version?
