Playready DRM playback issue

Hello,

We are trying to upgrade our player (actually in version 8.138.0) to the last version, but we are facing an error :

const playerConfig = {
      key: 'xxx',
      ui: false,
      playback: {
        autoplay: true,
      },
      advertising: {},
      logs: {
        level: LogLevel.DEBUG,
      },
      tweaks: {
        max_mpd_retries: 0,
        disable_retry_for_response_status: {
          [HttpRequestType.MEDIA_VIDEO]: ERROR_TO_SWITCH_CONFIG,
        },
      },
      adaptation: {
        startupBitrate: that.playerStreamConfig.webConfig.initialBitrate,
      }
}
const playerSource = {
      dash: 'url_to_the_stream_url',
      drm: {
            playready: {
              LA_URL: 'url_to_the_license_url',
              utf8message: true,
              plaintextChallenge: true,
              headers: {
                 'Content-Type': 'text/xml'
              }
            },
          }
    };

On some device we are adding this but not on all the device

   utf8message: true,
   plaintextChallenge: true,
   headers: {
       'Content-Type': 'text/xml'
   }

That is working on 8.138.0 but on your last version (8.194.0) not here are the logs :

Thx in advance for your help.
