Empty reply from server after updating brand followed by immediately creating product

[flyingL123]

I am attempting to first update a brand, then create a product using the Bigcommerce API. I am doing so with the following code:

Bigcommerce::updateBrand(48, ['name'=>'Del Sol']);
echo "Brand Updated";
Bigcommerce::createProduct(['name'=>'New Test'.rand(), 'weight'=>3, 'price'=>3, 'availability'=>'available', 'categories'=>[1582], 'type'=>'physical']);
echo "Product Created";

This results in an Bigcommerce\Api\NetworkError being returned, with the message Empty reply from server.

If I run either of the commands above by themselves, the request succeeds. If I switch the order of the commands, so that the product is created and then the brand is updated, both requests succeed. However, when I run them as shown, the updateBrand command works correctly, but the createProduct command hangs for a while and then throws the Bigcommerce\Api\NetworkError.

Why would this be happening?

@flyingL123 can you provide me the store domain that you are noticing issues with?

[flyingL123]

The domain is http://mikedev.mybigcommerce.com/. Store hash is grbzj9js. Please let me know if you need anything else.

This looks like a test site, any reason I cannot grab the api credentials from admin and run a few tests directly to the site?

[flyingL123]

That's totally fine. You can do whatever you need.

I am not able to reproduce, see the attached screenshot as well as code that I used to produce it.

Could it make a difference that I am using oAuth and you aren't?

[aleachjr]

It should not matter. I do see the error that you had in the logs, it is reported as 409 Resource Conflict. Can you try again?

[aleachjr]

Also, out of curiosity, how are you using the PHP client with oAuth? We have not released this functionality in this library.

[flyingL123]

I just made some minor changes to the client to support oAuth: https://github.com/flyingL123/bigcommerce-api-php

I'm receiving this error consistently 100% of the time. The only difference between our code is that I'm using oAuth. Are you sure this wouldn't cause the problem? Could I provide you with the oAuth credentials so you could try it that way?

Also, are you sure that 409 resource conflict is a result of this? Normally a resource conflict gets returned as a client error, not the network error like I'm seeing here. I had received resource conflict errors earlier today for other reasons, so I just want to make sure you aren't seeing that and assuming it's from this code.

I just tried again a few more times, and received the same error.

Hi @aleachjr - I just tried the same code using standard Auth instead of oAuth, and it worked. Any idea why this is happening?

[aleachjr]

Upon looking at your branch, I also notice that you are using code that is 40 commits behind current master. I would suggest that you update your branch to the latest master code and try again. If that continues to fail, try this without using oAuth as it is not currently supported in the library. I am unable to test this using unsupported code at this time.

[flyingL123]

I understand. The problem is that Bigcommerce requires oAuth for certain things, like webhooks, but then your SDK's don't support oAuth, so it puts us developers in a tough position. Are you at least able to see if there are any errors occurring on your server that would cause this empty response?

I understand that you can't just take my word for it, but there is nothing in my branch that would be causing this. It works in every other scenario as expected. It even works fine if you just change the order of the the two commands we're discussing.

Thank you for your help.
