frames-devs

How can I figure out why this frame embed code isnt working? The manifest dev tool isn't giving me a reason its not valid. 

This is the miniapp metadata returned in my apps html on the manifest.json home url yet its not rendering as a frame

```
<meta name="fc:miniapp" content="{
  "version": "1",
  "imageUrl": "https://boj.zucity.org/boj-og.png",
  "button": {
    "title": "Get Leverage",
    "action": {
      "type": "launch_miniapp",
      "name": "BoJ Leverage Market",
      "url": "https://boj.zucity.org/?miniApp=true"
    }
  }
}"
```
