Error "invalid id" when trying to add product to sales channel

[Andrea49]

I am trying to add a product to a sales channel using Graphql Admin API, this is my request:

mutation MyMutation {
    productPublish(input: {id: "%s", productPublications: {publicationId: 
    "gid:\/\/shopify\/Channel\/84635386114"}}) 
    {
        userErrors {
            field
            message
        }
    }
}

When I try to add it, I get this error 

{"data":{"productPublish":null},"errors":[{"message":"invalid id","locations":[{"line":4,"column":17}],"path":["productPublish"]}],"extensions":{"cost":{"requestedQueryCost":10,"actualQueryCost":1,"throttleStatus":{"maximumAvailable":1000.0,"currentlyAvailable":999,"restoreRate":50.0}}}}

Do you have any idea why I get this error?
I request the channel Id and this is the response

{"data":{"channels":{"nodes":[{"id":"gid:\/\/shopify\/Channel\/84635386114","supportsFuturePublishing":true}]}},"extensions":{"cost":{"requestedQueryCost":12,"actualQueryCost":3,"throttleStatus":{"maximumAvailable":1000.0,"currentlyAvailable":997,"restoreRate":50.0}}}}

And I'm sure the product id is correct

Hey @Andrea49 - this is odd. Would you be able to share an X-Request ID from the response headers on the latest request that returns that error? Happy to look into this further with you. 

Hope to hear from you soon - let us know if we can clarify anything on our end.

Thanks, I was able to resolve the issue but just adding {published: true} to the productCreate() mutation input, and it was published to my online store
