Handler function does not contain run?
As I was writing my plugin, this weird error came up that stops my plugin from functioning properly: 
`Error in command conStrest Script at path /Users/laptopname/Desktop/Sketch Plugins/plugin-directory/plugin.sketchplugin/Contents/Sketch/my-command.js does not contain a handler function named: run.` What does this mean?

I gave a handler/action list to a function like so: 

```json
{
  "compatibleVersion": 3,
  "bundleVersion": 1,
  "commands": [
    {
      "name": "array",
      "identifier": "list-array-doohig",
      "script": "./my-command.js",
      "handlers" : {
          "actions" : {
              "OpenDocument.finish" : "conStrest"
          }
      }
    }
  ]
}
```

I thought if I gave a handler a function name, the name "run" wasn't necessary anymore?

The JS file is as such: 

`export function conStrest(context) {
  context.document.showMessage("It's alive 🙌")
}
`

I just tweaked the function name to see if things would work... it didn't...
