Can not update the Variant Price using the ShopifyAPI

I am facing a problem - can not update the price of the variant using the ShopifyAPI..

while updating the price of the variant, it is giving the error

@remote_errors=#<\ActiveResource::ResourceInvalid: Failed. Response code = 422. Response message = Unprocessable Entity.>, @validation_context=nil, @errors=#<\ActiveResource::Errors:0x000000029eb1d0 ...>>, @messages={:base=>["Options are not unique"]}

'\' after '<' is required to show the error, otherwise stack overflow is hiding the error.

as required on another question
on production store, the request id is "38f5c3b3b7bdf4433724a845c6df4571"
on test store, the request id is "6050f165586b631e81b840dc0e1e6807"

This is a bug in ActiveResource 3.1+.

I have opened an ActiveResource pull request, but I am still awaiting a response at the moment.

I have committed a workaround for this bug in shopify_api v3.0.1, so upgrading this gem will fix this issue for you issue.

@messages={:base=>["Options are not unique"]}

That's your problem. Looking at the logs you're using POST to submit the request, which is used for creating new objects. Shopify is recognizing that there's already a variant with the specified options and refusing to create a new one.

If you use PUT as your HTTP method instead, Shopify will correctly interpret this as an update and everything should be fine.
