Apollo Client sending requests to wrong uri

Question

I'm using Apollo Client to send requests to a graphql server. I created a link with apollo-upload-client since I need it for what I'm doing. The client is defined as follows:

const link = createUploadLink({
    uri: 'http://localhost:4000/graphql'
});

const client = new ApolloClient({link});

However, when I try to make a mutation, it sends the request to http://localhost:3000/graphql instead. This results in a failed request, as that is not where the server is. Strangely, requests work fine if I specify the uri directly in the client like this:

client = new ApolloClient({uri: 'http://localhost:4000/graphql});

At first I thought it might be a problem with createUploadLink, but even using HttpLink causes this problem. Why does the client request the wrong address when using links?

It turns out the problem was where I was importing ApolloClient from. I was originally importing it from apollo-boost. It worked when I imported it from @apoloo/client.
