lambda.role without colons throws error

[ivarprudnikov]

Prerequisites

• [x] I am running the latest version. (up upgrade) v1.3.0
• [x] I searched to see if the issue already exists.
• [x] I inspected the verbose debug output with the -v, --verbose flag.
• [ ] Are you an Up Pro subscriber?

Description

First ever deploy ends in panic and all hell breaks loose. In short I used the AWS execution role name (foobar) instead of its ARN (arn:aws:iam::990099999999:role/foobar).

Error message panic: runtime error: index out of range was not helpful, had to fish out source code and realize that it expects semicolon in role, which lead me to the usage of actual ARN.

Failing line in your codebase: https://github.com/apex/up/blob/master/platform/lambda/lambda.go#L945

Steps to Reproduce

• app.js

const http = require('http')
const { PORT = 3000, UP_STAGE } = process.env
http.createServer((req, res) => {
  res.end('Hello World from ' + UP_STAGE)
}).listen(PORT)

• up.json

{
  "name": "fancy-api",
  "profile": "apex_up",
  "regions": ["eu-west-1"],
  "lambda": {
    "role": "foobar"
  }
}

Then run $ up -v

thanks! definitely need some validation there

[ivarprudnikov]

Is there any validation happening at the moment, at the time up.json is parsed maybe? I might chip in and do some minor pull request if necessary.
