youtube-v3-api Channel list error - youtube-api

Question

When I use the test form on the page https://developers.google.com/youtube/v3/docs/channels/list to get my upload ID I do not get the upload ID information in the output.
200 OK

The command being used to generate this request is
GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=StraconisChannel
The part that confuses me is I'm doing the same thing as suggested by a tutorial I was following, the only thing I'm changing is the channel name and using my channel name instead. His output looks like this:

}
]
}
The request used for his results:
GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=techguyweb
I activated the Authorization using OAuth 2.0 so I'm not sure what the issue is.
Edit
A comment stated because it was my youtube username and not my google plus account name. I forgot to put this in to provided information as well. Which is the same result.

Answer 1

It returns the correct response if you specify channel ID instead of channel name (I got the information via HTTP request but it should work the same for the way you're trying to get the response).
