Upload thumbnail to Youtube API using curl

I'm using curl with YouTube API v3 to create a broadcast, modify video title, etc without any issues. My problem is when I try to add a thumbnail to a video using the docs from Google.

Here is my sample with the keys changed for security reasons:

curl --request POST -v \"https://youtube.googleapis.com/youtube/v3/thumbnails/set\?videoId=RoZypUhZY04\&uploadType=media\&key=mykey" \  --header 'Authorization: Bearer my_access_token' \  --header 'Content-Type: image/jpeg'\  -F 'file=@/Users/adviner/Projects/Prototypes/VendorAPI/source/YouTube/YouTube-BOS.jpg'\  -F 'filename=YouTube-BOS.jpg'

I have tried:

-F 'image=@/Users/adviner/Projects/Prototypes/VendorAPI/source/YouTube/YouTube-BOS.jpg'\

In the documentation it says to use the following URL to POST the image:

https://www.googleapis.com/upload/youtube/v3/thumbnails/set

but when you view the sample it says to use:

https://youtube.googleapis.com/youtube/v3/thumbnails/set

I have tried both and it seems that the images are properly uploaded but I get the following errors:

For the first URL: https://www.googleapis.com/upload/youtube/v3/thumbnails/set

{"error": {"code": 400,"message": "Media type 'image/jpeg; boundary=------------------------136ebfc0c8146cb8' is not supported. ","errors": [      {"message": "Media type 'image/jpeg; boundary=------------------------136ebfc0c8146cb8' is not supported. ","domain": "global","reason": "badRequest"      }    ],"status": "INVALID_ARGUMENT"  }}

When using the URL: https://youtube.googleapis.com/youtube/v3/thumbnails/set

{"error": {"code": 400,"message": "The request does not include the image content.","errors": [      {"message": "The request does not include the image content.","domain": "youtube.thumbnail","reason": "mediaBodyRequired","location": "body","locationType": "other"      }    ]  }}

Any ideas on what I'm missing?

Thanks
