Unable to remove item from cart about co-cart HOT 25 CLOSED

When you say the delete request was SUCCESS with status 500 does that mean it is deleting the item but still returns an error response?

from co-cart.

@seb86 Sorry for my english and No it did not delete the item in the cart.

from co-cart.

OK I will look into the issue. Could you please provide me with your WooCommerce system status report. Thank you.

from co-cart.

@Janie20 I have not been able to replicate your issue. I was able to remove an item using Postman with no problems.

Did you add the item via Postman first or did you add the item via the site first then try to remove it via Postman because it can not see your browser session?

Steps I took to remove item in Postman.

1. View cart - cart is empty
2. Add an item - cart returned with item
3. View cart - cart returns with item
4. Delete item - item is removed
5. View cart - cart is empty

from co-cart.

I did the same steps that you took , but i would still get the error on step 4.
I'm new to woocommerce , is this the system report you are looking for ?

Thank you for sharing your system report. Can you tell me why you have WP REST API installed? It's already part of WordPress. That could be causing some issues. Please disable it and try again.

from co-cart.

I deactivated it and try again , but still getting the same error result.

from co-cart.

Are you using authentication when removing the item?

from co-cart.

Can you make sure the item key is also correct.

from co-cart.

No, I'm not using authentication, when removing the item. I make sure my cart is not empty as you can see in the first picture , then I tried to remove the item , I only put the cart_item_key on the body.
I can't figure out where I'm wrong , am I missing any steps here ? Really appreciate your help !

from co-cart.

I see what you are doing now. You are adding the cart_item_key as form-data when you should be adding it to the parameters. Clear the form-data and click on "Params" next to the big blue "Send" button.

Then add the key and value there. Then press "Send".

from co-cart.

Oh, I did not know that , I tried what you suggest and this is my result.

from co-cart.

Can you disable all plugins execpt for WooCommerce and the Cart REST API and try again after refreshing your permalinks to flush the rewrite rules please.

from co-cart.

still not working ...

from co-cart.

Then the only thing I can think of is that there is something wrong with your Postman software because you should only get that error if the cart_item_key is not added as a parameter which you have done.

from co-cart.

Are you able to run the same tests with your site online?

from co-cart.

You mean publish my website on the internet ?

I used ngrok to run my site and repeat the steps ( with only two plugin activated which is the Cart REST API and WooCommerce , sadly I'm still getting the same result.

This is the screenshot capture on the ngrok terminal

from co-cart.

This is so weird. If the body is used to apply cart_item_key with form-data set it does not send the item key as a string so reports the error.

If posted with x-www-form-urlencoded set, it works.

from co-cart.

But the best option is still to use the "Params" to apply the cart_item_key. Works every time for me so what I would like you to do is the following:

1. View Cart - (GET) https://sebdumont.xyz/dev/wp-json/wc/v2/cart - Does it say "Cart is empty!"?
2. Add Product - (POST) https://sebdumont.xyz/dev/wp-json/wc/v2/cart/add?product_id=60 - Does it return item data in the body response?
3. Do step 1 again to make sure the product was added.
4. Remove Product - (DELETE) https://sebdumont.xyz/dev/wp-json/wc/v2/cart/cart-item?cart_item_key=072b030ba126b2f4b2374f342be9ed44 - Does it remove the item?
5. Do step 1 again to make sure the cart is empty again.

If that fails then I will look further into the issue. I would just like to see what you get after running this test.

Thank you.

from co-cart.

@Janie20 Let me know when you have run the tests as I asked above. Thank you.

from co-cart.

@seb86 I have founded whats the problem that causing the error , it turns out to be the cart item key that I get was the reason causing the error. I'm not sure if this is the main reason, but it works perfectly fine after I done some configuration on my site, then I go create a new product , and the key that generated become slightly different as I realize the key generated now start with a number instead of an alphabet like my previous cart item key. Now it works perfectly fine. Thank you for answering my question , really appreciate the help ^_^

from co-cart.

@Janie20 Can you tell me what configurations you made to your site that you think helped fix the issue?

If the issue is with the cart item key starting with a letter rather than a number then that will need to be confirmed.

Do all your products item key start with a letter or number? I will comfirm on my end to see if that is the case. So far no one else has reported this issue.

from co-cart.

I can confirm that products cart_item_key can start with a letter or number. When it starts with a letter it is unable to validate the value not being a 0. See line 362-364 on removing an item.

I will change this validation and put out a release soon.

from co-cart.

The same validation will be applied to restoring and updating an item.

from co-cart.

OK I have pushed changes @Janie20.

Can you download the update and run your tests again please to confirm.

Let me know if the issue is resolved afterwards. Thank you.
