GraphQL mutation: Invariant Violation: Must contain a query definition

Question

I am trying to make a mutation call to my graphQL server from a react application. The react code looks like the following:

client.query({   query: gql`     mutation{         addTeam(input:{name:"Somename", label:"somelabel"})         {error, status}     }`  }).then((resp: any) => {       console.log("Success", resp);  }).catch(err => {       throw err;  }) 

And I am getting the following error:

But if I change the same request, from mutation to query, and make the necessary changes in my node-graphQL-server to handle it as query instead of mutation the same code works.

Apollo-Client Mutation docs says

In GraphQL, mutations are identical to queries in syntax, the only difference being that you use the keyword mutation instead of query...

Oh and BTW, the same mutation query WORKS in Playground. Please help guys, my work is kinda stopped coz of this issue.

Thanks!

You should use the mutate method of the client for mutations, not the query method. The options for the method can be found in the docs. Apollo is opinionated about how queries and mutations are treated, so each method has different options that are appropriate to each operation's behavior (for example, mutate includes a refetchQueries option).

client.mutate({   mutation: gql`     mutation {       addTeam(input:{name:"Somename", label:"somelabel"}) {         error         status       }     }`, })
