Youtube resumes downloading 400 bad requests

Question

I am trying to resume downloading on youtube using rest api clients. STEP 1:

https://www.googleapis.com/upload/youtube/v3/videos?uploadType=resumable&part=snippet,status,contentDetails

Headings

Authorization Bearer ya29.1.AADtN_UxUBz459k8HO_gropj2SW6ShlFsqBqJMXI3HVfcE4lKWkR-gq4_Tj0j6Oqb-oo_qnE Content-Length 278 Content-Type application/json; charset=UTF-8 X-Upload-Content-Length 1393167 x-upload-content-type application/octet-stream 

Body

 { "snippet": { "title": "My video title", "description": "This is a description of my video", "tags": ["cool", "video", "more keywords"], "categoryId": 22 } } 

I get a response of 200 Ok. I will retrieve the url that is used in a further request.

STEP-2:

https://www.googleapis.com/upload/youtube/v3/videos?uploadType=resumable&part=snippet,status,contentDetails&upload_id=AEnB2UqmDFhqQrOpbIgMp_E_bBUJeKfRyJfjfjfjfjfjfjfjfjfjfjfkfkf

Headings

 Authorization Bearer ya29.1.AADtN_UxUBz459k8HO_gropj2SW6ShlFsqBqJMXI3HVfcE4lKWkR-gq4_Tj0j6Oqb-oo_qnE Content-Length 1393167 Content-Type application/octet-stream 

Body

VideoFile - abcd.mp4

When I try to upload a file, it returns 400 with the following answer.

 { error: { errors: [1] 0: { domain: "global" reason: "badRequest" message: "Invalid Upload Request" }- - code: 400 message: "Invalid Upload Request" }- } 

I tried to execute the above request from the client - Advanced REST API and Postman REST client from Google chrome, Java program - wherever it returns 400. Can someone please indicate what error I am making in step 2. It would be very useful.
