How about just check if (bid.gdprConsent), to avoid "Cannot read property of null"?

[jsnellbaker]

Additionally to @aodinok suggestion, the gdprConsent object doesn't exist in the bidRequests but rather in the bidderRequest object. This additional variable needs to be added to the buildRequests() function call.

This would naturally affect the remaining GDPR related code below.

This line can be just: gdprSignal,

@jsnellbaker any chance you could review the code?

[jsnellbaker]

Hello @erolosty I'm sorry about the small delay here. I spotted an issue that needs to be addressed otherwise the consent information won't be passed through in your request, please see the in-line comment below.
