GraphQL error: Schema is not configured for mutations

[ilan-schemoul]

Hello,
when I loginWithPassword({ email, password }, apolloClient) it returns the error GraphQL error: Schema is not configured for mutations. Yet I've ofc did initAccounts(); then loaded with loadSchema the schema and the resolvers, that you can see here :

// schema
[`
  type User {
    _id: Int
    name: String
    emails: [Email]
    password: String
    admin: Boolean
  }
  
  type Email {
    address: String
    verified: Boolean
  }
`];
// resolvers 
{
  Query: {
    users(_, args) {
      return User.findAll({ where: args });
    },
  },
};

Your package seems good but is very widely undocumented unfortunately.
And obviously after all that I've makeExecutableSchema and created the apollo server with the function createApolloServer.

I don't understand what's wrong.
Here are defined mutations of this package and here these mutations are loaded.
I really really need your help.

Oh okay I forgot to put into my schema {} mutation: Mutation
