"inventory_quantity"=>"expected String to be a Integer"} on variant.save

[jacksonSingleton]

Issue summary

Write a short description of the issue here ↓
When calling save on a product variant, it returns the error 'request': {"inventory_quantity"=>"expected String to be a Integer"} (ShopifyAPI::Errors::HttpResponseError) despite not modifying inventory quantity at all.

Here's my code block that the error is tracing to

def modify_inventory_management(item)
  puts item.inspect
  item.fulfillment_service = 'manual'
  item.inventory_management = 'shopify'
  item.save
end

Expected behavior

What do you think should happen?
So my code was previously working before upgrading to v10.x from gem version 9.5.1. I would assume it would just write and give a 200 status

Actual behavior

What actually happens?

Details

`'request': {"inventory_quantity"=>"expected String to be a Integer"} (ShopifyAPI::Errors::HttpResponseError)`

Steps to reproduce the problem

1. Just calling product.variant[0].save is producing the problem even without modifying any fields

Logs

If applicable, enable the logs as described in the README, and paste the relevant portion here.

So here's the output of product.variant.first.inspect where on option1 the inventory_quantity field is correctly set to 0 rather than a string as described in an error

Hello! Having the same issue here. Did you have any luck solving this?

shopify_variant = ShopifyAPI::Variant.find(id: variant_shopify_id, session: ShopifyAPI::Context.active_session)
shopify_variant.save

ShopifyAPI::Errors::HttpResponseError ({"inventory_quantity"=>"expected Hash to be a Integer"})
If you report this error, please include this id: 00f34b32-2e11-4529-b95b-5ae77e4330a7.

Also tried to manually set inventory quantity to integer but same error

shopify_variant = ShopifyAPI::Variant.find(id: variant_shopify_id, session: ShopifyAPI::Context.active_session)
shopify_variant.inventory_quantity = 0
shopify_variant.save

ShopifyAPI::Errors::HttpResponseError ({"inventory_quantity"=>"expected Hash to be a Integer"})
If you report this error, please include this id: d5a0fca5-ccbc-4b1c-904b-51cbdc224c58.

Did you manage to solve this? I am also having the same issue.

[schappim]

One thought: What happens if you change the API version?

[caseyprovost]

Same here on API version "2022-07"

-- EDIT--

Updating to 2022-07 results in the exact same error

[caseyprovost]

For anyone still stuck (like I am)...there is a workaround. Simply use the GraphQL Admin client instead of the REST one. I've found it to work when the REST API client is broken for each and every case. Including this one, but also deleting collections and variants. Not a great fix, but it works.

[tiredenzo]

Same issue here. Would be nice to have a fix, thanks in advance

This issue is stale because it has been open for 60 days with no activity. It will be closed if no further action occurs in 14 days.

[schappim]

Bump to keep this open. Has Shopify said they’re depreciating the REST client? It’d be nice to get a clear “if you’re building new apps, don’t use this API”.

[benichu]

having the same kind of errors as one described in the thread:

ShopifyAPI::Errors::HttpResponseError ({"inventory_quantity"=>"expected Hash to be a Integer"})

Tried versions 10.1.1 and 12.3.0 of this library (REST mode) with the same result.

[schappim]

@benichu we've given up on the Shopify Gem, and just built our own wrapped for the REST API.

[jacksonSingleton]

Sorry for the late reply for anyone searching. I had to solve this by just using REST calls with anything new that I write. Kinda sucks because I had a ton of work set up using the gem. Gotta love the Shopify devex.

[benichu]

You both confirmed what I thought.
I really need to decide what to do, I tried to look into the gem itself, but I can't be bothered with that Sorbet misdirection sprinkled everywhere... Also, I don't care about the GraphQL version, I have other things to worry about than adding a new concept to communicate with HTTP remote services.
I guess I'll write a quick REST wrapper like you both did to give me time to reconsider my next move with the Shopify integration

We can't have good and lasting tech anymore, it feels like big tech companies like Shopify and others are on a treadmill to change services and libraries for the sake of it.

When I think that I only started that rabbit hole of a waste of time because of an Unauthorized ([API] Invalid API key or access token (unrecognized login or wrong password)) error out of nowhere 🤷

All I want is to be able to integrate my application with Shopify and forget it. I don't care if it means locking a client library and API backend versions and foregoing some "new amazing" features. I honestly don't want to have to read every developer announcement and deprecation notice required by the "new" growth strategy...
I just want to keep on synchronizing 2 product catalogs for god's sake 😢
