Cannot read properties of null (reading ‘verifyCard’)

Hey there, @seanconklin! Thanks for contacting us. I’m happy to help you.

That’s not good. Let’s investigate to figure out what is going on.

To confirm, it is not all credit card payments that have this issue, correct?

Can you please share the screenshot you got from the customer so we can take a look? please remove any sensitive information from it before sharing it.
I recommend using https://snipboard.io. You can share the direct link to the image as a response to this topic.

Furthermore, I’d like to understand your site properly. Please share with us the necessary information below for us to investigate the issue further:

System Status Report which you can find via WooCommerce > Status > Get system report > Copy for support.
Fatal error logs (if any) under WooCommerce > Status > Logs. Then you can use the selector to search for Fatal Errors.
You could copy and paste your reply here or paste it via https://gist.github.com/ and send the link here.

Lastly, it would really help if you could enable debug mode and test mode and run some test orders to see if you are able to trigger the issue.
If the issue is triggered while debug mode is active it can generate more error logs that might help us investigate this.
You can choose to log API requests directly on the checkout page, save them to the?WooCommerce > Status > Logs?page, or both.

Looking forward to your reply.

Have a wonderful day!

Here’s the screenshot that I received: https://snipboard.io/L2c1Tr.jpg

There’s no fatal errors showing up in the Woo > Status > Logs area.

### Status report information ###

Generated at: 2024-08-02 10:34:35 -07:00

We’ve received three or four Braintree credit card orders today, so the problem seems to be getting better on its own!

Unfortunately though we did hear from one other customer who had trouble with payment. All I heard from C/S on that one was “payment is giving the null error message again.?He is older and does not know how to clear his history”. So we’re not out of the woods yet, but things are looking up overall.

Hello Sean Conklin,

Thank you for your reply.

Are you using any custom code to modify Checkout fields?
I am asking because a similar issue was reported a year ago and our devs updated the plugin to fix that problem.

Since the Checkout Block relies on JS, it is possible that this problem was caused by a JS cache on the customer’s browser.

I am glad you have received multiple orders via Braintree credit card.
But as you said, we are not out of the woods yet and must observe this for some more time.

Feel free to reply if you have more information to share. ??

Best regards.

We’re not doing any checkout modifications. These days I remove those whenever I find them since it’s (a) disruptive to the customer and (b) incompatible with the Express Checkout methods that have become very popular, bypassing checkout fields accordingly.

It’s possible caches may have something to do with this one. I did flush all of the WP Engine caches earlier yesterday so the timing would line-up there. We’ll keep an eye on it…

Hi @seanconklin

I’m glad to hear that you’re not using any custom code to modify Checkout fields, as this could potentially lead to conflicts.

The issue with the ‘null’ error message could indeed be related to cache, especially if flushing the WP Engine caches seemed to coincide with an improvement.

Additionally, head over to WooCommerce → Status → Tools, and do the following:

• WooCommerce transients – Clear
• Expired transients – Clear
• Clear template cache – Clear
• Capabilities – Reset Capabilities
• Clear customer sessions -Clear
• Product lookup tables – Regenerate
• Regenerate the product attributes lookup table – Regenerate

Next, it would be a good idea to ask customers who encounter this issue to clear their browser cache as well, as outdated cache files on their end could also contribute to the problem.

Please continue to monitor the situation and don’t hesitate to reach out if the issue persists or if you notice any new patterns. We’re here to help.

Hi @seanconklin

I’m marking this topic as “resolved” due to recent inactivity. If more assistance is needed, feel free to post back here or open a new topic.

Thanks!

I don’t consider it resolved. I can’t spend the client’s budget going down rabbit holes, but I do believe that in time there will be more clarity on this problem. I’m keeping an eye on things. We released Stripe (a requirement for the Browser Demand payments anyhow) and that provides a secondary CC form as well, but the client may prefer the Braintree CC form, so we’ll see how this goes. I suppose we’ll have to open a new ticket then when there’s more details.

Hi @seanconklin

You’re right, it’s important to keep an eye on the issue to gather more details. It will help us understand the root cause and find the appropriate solution.

In the meantime, I would recommend you to keep the Stripe as a secondary CC form. This will provide an alternative payment method for your customers and may help to avoid potential transaction issues.

Should you encounter any further issues or if you have more details about the problem, please don’t hesitate to open a new ticket. We’re here to help and we appreciate your patience as we work to resolve this issue.

Thanks!
