Issue

When I query the following license server https://rbm-rtbf.live.ott.irdeto.com/licenseServer/widevine/v1/rbm-rtbf/license, I got as response the following error messages

server reports: {"code":100100,"message":"The request is invalid. Error while parsing: contentId. Parameter null not expected as an array"}
server did not issue license, make sure you have correctly pasted all the required headers in the headers.py. Also check json/raw params of POST request.

Well, the error message you received very clearly points to a misconfiguration of the request. Make sure your script generated request has exactly the same fields, datatype, structure, etc. (I suggest using chrome devtools to do so)

cmoulliard commented

I followed exactly the instructions:

  1. Opened Firefox browser and enabling dev tools console
  2. Got the video link https://www.rtbf.be/auvio/detail_cobalt-l-envers-du-reve-electrique?id=2943776&t=649 and starting to play it
  3. Filter the resources under network tab to get the mpd url https://c9851ec-az-westeurope.fsly.cdn.ebsd.ericsson.net/rtbf/auvio/assets/2943776_6BA97Bb/materials/KaFVNUi0Gg_6BA97Bb/vod-idx-2.ism/.mpd?
  4. Filter the resources (see screenshot) to get the Request URL from Headers of the license URL like the curl request
  5. Convert the curl request to Python using curlconverter.com web site
  6. Copy/paste the content within the headers.py before

  1. Launch python3 l3.py
  2. Pass the mpd url
  3. Pass the license url

Question: From where the tokenId, provider, releasePid are coming from and why do we need them ?

I followed exactly the instructions:

  1. Opened Firefox browser and enabling dev tools console
  2. Got the video link https://www.rtbf.be/auvio/detail_cobalt-l-envers-du-reve-electrique?id=2943776&t=649 and starting to play it
  3. Filter the resources under network tab to get the mpd url https://c9851ec-az-westeurope.fsly.cdn.ebsd.ericsson.net/rtbf/auvio/assets/2943776_6BA97Bb/materials/KaFVNUi0Gg_6BA97Bb/vod-idx-2.ism/.mpd?
  4. Filter the resources (see screenshot) to get the Request URL from Headers of the license URL like the curl request
  5. Convert the curl request to Python using curlconverter.com web site
  6. Copy/paste the content within the headers.py before

I've a similar issue. Did you find a fix?

Did you find a fix?

Unfortunately no :-(

thejackal2017 commented

Hi , I tried on another link and this message also appeared , to fix this

edit the script add a custom request to the array and try to remove the "params=params" from it and you will get the keys

responses.append(requests.post(url=lic_url, headers=headers.headers, data=raw_request))

don't forget to use fresh headers .

Regards
