A rendering error occurred: Cannot read properties of null (reading 'fields').

I get the error message when trying to access member benefits on chrome edge and cellphone.

I am able to sign in and use my account normally except the membership benefits page.  

Thanks for confirming! That helps narrow things down quite a bit. Since you're able to access the rest of your account normally and have already tried multiple browsers, clearing your cache, and using incognito mode, this appears to be specific to the Xfinity Membership benefits page.

With other members reporting the same error, we'd like to look into whether there's a broader issue affecting access to Membership benefits rather than have you continue repeating troubleshooting steps.

One thing we haven't checked yet: Have you tried accessing your Membership benefits through the Xfinity app instead of a web browser? If so, are you receiving the same error there?

No I can not access through the app either, it is the same error

Good Morning, @user_b6vpah! Thank you so much for taking the time to reach out to us here on the Xfinity Forums. I am very sorry to hear about the experience with reaching the Xfinity Membership page, it certainly not what we want for our customers. Have you attempted incognito mode on the browsers?

Yes, I have tried incognito browsers as well. 

Same issue, and yes, I've tried everything suggested here.

@XfinityJeffB​ Do you mean a browser's private mode? I just did and got the same result. I check Xfinity's member rewards every week, have been for years, and considering how many others have been getting this message today, something must have changed this week on the Xfinity site.

Yes, that is exactly what I meant. We can try digging a little deeper on this for you, it may require a ticket, but we're here to help and do all we can.

Thanks for providing us with an update, @Jonathan75. From the public post & comments I have seen this far it looks like it appears the issue has been resolved on a large scale. Those rewards certainly move fast, guess people were still watching that page like a hawk while things were being worked on. 

It's still not working for me. Getting the same error form both browser and app since yesterday afternoon. It's clearly a website issue not handling null data correctly under specific conditions. Get the website team to check the logs, monitor for errors, and debug! Stop wasting customers time asking them to clear cache and data. Websites need to handle these conditions, sign users out, and clear the cookies/cache itself. 

@XfinityJustinM​ It is not working for me still as of right now. Someone needs to fix this ASAP. This is ridiculous. You're an internet provider that can't fix your own website?

@user_zwxp9q

Thanks for reaching out to us have you tried any of the troubleshooting steps that are listed on this post ?

@XfinityOrlandoM​ yeah all of them. It's not an us problem. It's an Xfinity problem.

@user_2qqlyw​ Sounds like much like me you have wasted far more time than any of this is actually worth.

@user_lruigt​ There is no fix.

Company worth millions and millions of dollars can't fix something with a giant team of overpaid "professionals", something I used to fix by-myself on a DAILY basis easily when I did IT for nickels and dimes. LMAO

Huge L comcast

Update, it worked only once on Internet Explorer, but now the problem is back when I tried it again.

I was able to get in once yesterday going through some backwards way. I was able to redeem the $1 rental. But now I can't remember how I did it and cannot get back to view current deals.
