Solved: Error when reducing product quantity in cart - sporadic

[Chandra]

When some products are added to the cart and then the '-' button is clicked to reduce quantity of a product, a technical error pops up sporadically.

Technical Error: unable to save update quantity Details: Error thrown: [object Object] Text status: error

It appears this happens when there is more than one product in the cart. Please see screenshot.

I think this is an important bug since it affects the customer experience and the merchant loses money also. We have had some issues with customers ordering below the minimum order quantity for free shipping and claiming the bug affected their order.

I think I found the solution. I can confirm this is an nginx setting and not a thirtybees issue.

For anyone who has this issue, try adding the following lines to the nginx configuration within the server section:

 fastcgi_buffers 16 16k; fastcgi_buffer_size 32k;

Thanks all.

Not that I can confirm this, but I've filed a Github issue: https://github.com/thirtybees/thirtybees/issues/849

It would help if you could access the error log of your server and see the related error.

Absolutely no related entries in the thirtybees log accessed from backoffice.

Were you thinking another log?

This could be some other error, as i'm not experiencing such issues neither on 1.6 ps Theme in live shop or community-default on current testing work in progress.

But I do think that those error messages should not have white-space: nowrap; setting as on mobile devices the message field becomes scrollable 🙂

This continues to be a recurrent issue. Please see attached.

 

My tb is fairly stock and I am community theme - can anybody guide on trouble shooting this. Thanks.

Hello @Traumflug

Found this in nginx logs - does this provide any direction? Looks like an nginx config that needs tweaked?

Don't know where this issue come from, as I can not replicate it on Stock TB install or on my Migrated installation.

Quantities are working in any directions without problems.

Is this happening on particular product, or on all products?

Are you using stock managment or not?
