NextMillennium adapter reading gdprConsent undefined

[hnkhandev]

Type of issue

Accessing property of possible undefined gdprConsent in request.

Description

Trying to access gdprConsent.gdprApplies and gdprConsent.consentString but not checking if gdprConsent is undefined: https://github.com/prebid/Prebid.js/blob/master/modules/nextMillenniumBidAdapter.js#L41-L55

Solution would look something like this:

if (gdprConsent || uspConsent) {
  postBody.regs = { ext: {} }
}

if (uspConsent) {
  postBody.regs.ext.us_privacy = uspConsent;
}

if (typeof gdprConsent !== 'undefined') {
  if (typeof gdprConsent.gdprApplies !== 'undefined') {
    postBody.regs.ext.gdpr = gdprConsent.gdprApplies ? 1 : 0;
  }
  if (typeof gdprConsent.consentString !== 'undefined') {
    postBody.user = {
      ext: { consent: gdprConsent.consentString }
    }
  }
}
