Pass contentId to onGetLicense

[yurtaev]

Some DRM providers require contentID for the license request.

Example for BuyDRM https://github.com/yurtaev/react-native-video/blob/example%2FDRM/storybook/stories/DRMExample/index.ios.js#L20

const getLicense = async ({ spcBase64, contentId }, props) => {
  const {
    drm: { headers },
  } = props

  const data = `spc=${spcBase64}&assetId=${contentId}`

  const response = await fetch('https://fp-keyos.licensekeyserver.com/getkey/', {
    method: 'POST',
    headers,
    body: data,
  })

  const key = await response.text()
  return key
}

I am using DRM provider and I am getting this error. This was working fine before:
the code in react native is:

return (
      <>
        <VideoPlayer
          ignoreSilentSwitch={'ignore'}
          onBack={this.goBack}
          videoInfo={toJS(videoDetails)}
          dash_auth_xml={this.state.dashXml}
          videoUrl={dashUrl}
          source={{
            uri: url,
          }}
          drm={{
            type: 'fairplay',
            certificateUrl:
              'https://hhhhhh.der',
            headers: {
              customdata: xml,
            },
            getLicense: (spc, contentId, spcBase64) => {
              console.log(spcBase64);
              console.log(contentId);
              return fetch('https://fp-keyos.licensekeyserver.com/getkey/', {
                method: 'POST',
                headers: {
                  'Content-Type': 'application/octet-stream',
                  customdata: xml,
                },
                body: `spc=${spcBase64}&assetId=${contentId}`,
              }).then((r) => r.text());
            },
          }}
        />
      </>
    );
