Widevine Error 170101

Hi everyone,

I'm looking for help with a license request for a on Sooka.my. My script keeps getting an "Invalid license challenge" error.

Video Link: https://sooka.my/watch/movie/1fc22f92-207c-4ff1-906c-3a33ceb31f84 (Note: This is a free-to-watch with a free account. Geo-restricted to Malaysia.)

The Error: {"code":170101,"message":"Invalid license challenge."}

 License URL: https://license.ctrp.astro.com.my/licenseServer/widevine/v1/astro/license?contentId=16fa4db42f4bfe44bde994fb756976ca-40a1412172098afb28a4-1

PSSH: AAAAMnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABISEBha/MX4ilFpt+3sGGraDMo=

My Headers and Payload: I am using a private L3 WVD and Python requests. I've matched the X-Media-Id and Authorization headers from my browser's network tab.

 Payload: { "contentID": "16fa4db42f4bfe44bde994fb756976ca-40a1412172098afb28a4-1", "contentType": 1, "authorizationToken": "eyJhbG...[REDACTED]", "authorizationTokenType": "1", "licenseChallenge": "[BASE64_CHALLENGE]", "playbackSessionCookie": null }

I am sending the JSON payload using Python requests with separators=(',', ':') to ensure there is no extra whitespace. My X-Media-Id and Authorization headers match the browser's network logs exactly.

Any help would be appreciated!

The extension method you provided worked perfectly. I was finally able to fetch the keys and decrypt the streams. Thank You
