Current behavior:

As soon as you include in your ionic.config.json a proxie list like:
"proxies": [
{
"path": "/v1",
"proxyUrl": "https://api.instagram.com/v1"
}
]

Run ionic serve, and then you remove this proxies variable, each time you try tu run ionic serve you get this error:

Uh oh! There's a syntax error in your ionic.config.json file: SyntaxError: Unexpected token } in JSON at position (line)

Ionic info: (run ionic info from a terminal/cmd prompt and paste output below):

It is very likely that you have left a trailing comma on the line above proxies. This makes the JSON invalid.

Hello,
I am currently experiencing this too. Would be great if there is a solution for this soon.
After adding a proxy, I ran ionic serve and this error message starts persisting. It occurs even after I undo the changes.

@zackxz This issue is old and we're not supporting CLI v2 anymore. If the problem persists when you upgrade your CLI, make a new issue.
