GraphQL productVariantsBulkUpdate not working python

[joant95]

I'm trying to update the prices of several variants in Shopify via the endpoint "productVariantsBulkUpdate" in GraphQL.

That's my code:

client = shopify.GraphQL()     
mutation = """
       mutation productVariantsBulkUpdate($variants: [ProductVariantsBulkInput!]!, $productId: ID!) {
          productVariantsBulkUpdate(variants: $variants, productId: $productId) {
            product {
              id
            }
            productVariants {
              id
            }
            userErrors {
              field
              message
            }
          }
        }
        """
params = {
          "variants": [
                {
                  "id":  "gid://shopify/ProductVariant/534676534632",
                  "price": "25.00"
                },
                {
                  "id":  "gid://shopify/ProductVariant/0987654321",
                  "price": "25.00"
                }
              ],
          "productId": "gid://shopify/Product/123456789"
         }
        
result = client.execute(mutation, params)
json_file = json.loads(result)
print(json_file)

I'm getting the following error:

{'errors': [{'message': "ProductVariantsBulkInput isn't a defined input type (on 
$variants)", 'locations': [{'line': 2, 'column': 47}], 'path': ['mutation 
productVariantsBulkUpdate'], 'extensions': {'code': 'variableRequiresValidType', 
'typeName': 'ProductVariantsBulkInput', 'variableName': 'variants'}}, {'message': 
"Field 'productVariantsBulkUpdate' doesn't exist on type 'Mutation'", 'locations': 
[{'line': 3, 'column': 15}], 'path': ['mutation productVariantsBulkUpdate', 
'productVariantsBulkUpdate'], 'extensions': {'code': 'undefinedField', 'typeName': 
'Mutation', 'fieldName': 'productVariantsBulkUpdate'}}, {'message': 'Variable 
$variants is declared by productVariantsBulkUpdate but not used', 'locations': [. 
{'line': 2, 'column': 12}], 'path': ['mutation productVariantsBulkUpdate'], 
'extensions': {'code': 'variableNotUsed', 'variableName': 'variants'}}, {'message': 
'Variable $productId is declared by productVariantsBulkUpdate but not used', 
'locations': [{'line': 2, 'column': 12}], 'path': ['mutation 
productVariantsBulkUpdate'], 'extensions': {'code': 'variableNotUsed', 
'variableName': 'productId'}}]}

Seems like Shopify doesn't know "ProductVariantsBulkInput" although it is a Shopify object.

What am I doing wrong?

Thank you in advance.

Hey Joant95 ,

I was just dealing with this issue. You might want to make sure that your version of the ShopifyAPI is up to date. Once you're on the right version, the query should work. 

Good luck,

Hey EmoryKPhan,

Thank you for your answer. Turned out that I had to use the unstable version.

So instead of passing the date of the current version you have to pass "unstable". Maybe it's also working with the current version of the API as well. I only tried it with an older version and it didn't.
