Unable to create a new product (deserialization error with object not found) about shopifysharp HOT 14 OPEN

I am experiencing the same issue.
I am not familiar with the code, but this is what is happening:

I am trying to create a product, the baseRequestMessage is the request to create (the POST), but it does a GET request first for some reason.

The API responds successfully, but the json returned has "products" as the root node, not "product", which is what is being sent through:

When deserializing, the node is not found, jToken is null and calling ToObject results in the null ref exception.

I resolved my issue, it was because of Shopify Domains.

I was using the first one, the Primary, when I switched to the other one, it worked. @pmartinciibo do you have multiple domains?

from shopifysharp.

Glad it's working for you guys! Just so I understand the solution, do you mind answering some questions I have if you have time?

1. The domain that wasn't working was a *.myshopify.com domain?
2. Using the second URL in ShopifySharp, the one that says it will redirect to a *.myshopify.com domain, is the one that actually works?
3. If they're both *.myshopify.com domains, which one was the original one for the store?

The one that was not working was my branded, primary domain (E.G., awesomestore.myshopfiy.com). The one that did work was more like a GUID (E.G. fffffff-f.myshopify.com). I don't remember for sure, but I suppose the latter was the original one, and I think I added the custom domain later.

Mine was the exact same, the original DNS was random letters and numbers (which works) and the primary custom domain was added later (which does not work).

Thanks @pmartinciibo! Would it be possible to debug the request and see if you can get the raw response body? It should be a property on the exception:

try
{
  // your code that throws an exception here
}
catch (ShopifyException ex)
{
  Console.WriteLine(ex.RawBody);
  throw;
}

That should give us the exact string that Shopify is returning, which will give a hint as to what can't be deserialized.

It doesn't look like a ShopifyException is being thrown.

from shopifysharp.

Oh, right, my bad. It's a null reference problem so it won't throw a ShopifyException. We'll need to look at the body before ShopifySharp tries to deserialize it, which is a little tricky. I'm going to write some test code and get back to you!

Sorry this slipped my mind. Thanks a ton @Jason-Powell-Sync! That helps me a lot. You said it's doing a GET request first? That's very strange and should not be happening, but it would explain why "products" is being returned as the GET request would mean Shopify is returning a list of products.

from shopifysharp.

I'm digging into this further on my side still.
I think it is doing a POST, but getting the GET response back. I am getting the same result on Postman.

from shopifysharp.

This is an issue on the Shopify side. This shows the exact issue I am having:

from shopifysharp.

Thanks for investigating, it's unfortunate the person in that forum post never got an answer from Shopify staff. I'd be curious to see the request and response headers if you have them, with your access-token and shop domain redacted. Maybe there's something in there that can clue us in as to what's going on.

Jumping in to second that using the second URL (redirects to ) also worked for me!
