What is missing from the application? Please describe.

I'd like to be able to specify nest arguments in a GraphQLNode object. The current structure doesn't seem to serialize the objects appropriately as the values are being treated as strings.

The query I am trying to build contains a nested parameter in the order argument list: customerLink: { ref: $customerRef }. When I attempt to use the withArgument method, the argument value is rendered as a string rather than a json object.

This is the query I am attempting to construct:

query OrderQuery ($count: Int = 10, $cursor: String = null, $ref: [String] = null, $status: [String], $customerRef: String!) {    
  orders (first: $count, after: $cursor,  ref: $ref, status: $status,  customerLink: { ref: $customerRef })  { 
    pageInfo { 
      hasPreviousPage 
      hasNextPage 
    } 
    edges {   
        cursor 
      node { 
        id            
        status
      }       
    }     
  }   
} 

Here is my code to build this query out:

public override GraphQLQueryNode GetQuery()
{   
    
    GraphQLNode orderNode 
        = new GraphQLNode('node')
            .withFragment('OrderHeaderFields');
    if (m_params.IncludeLines)
    {
        GraphQLNode orderItemsNode 
            = new GraphQLNode('items')
                .withNode(new GraphQLNode('edges')
                    .withNode(new GraphQLNode('node')
                        .withFragment('OrderLineFields')));
        orderNode.withNode(orderItemsNode);
    }   
    
    GraphQLNode parentNode = new GraphQLNode('orders')  
        .withArgument('first', '$count')
        .withArgument('after', '$cursor')
        .withArgument('ref', '$ref')
        .withArgument('status', '$status')
        .withNode(new GraphQLNode('pageInfo', new List<string> {'hasPreviousPage', 'hasNextPage'}))
        .withNode(new GraphQLNode('edges', new List<string> {'cursor'})
            .withNode(orderNode));      
    if (m_params.CustomerId != null)
    {            
        parentNode.withArgument('customerLink', new Map<string, object> { 'ref' => '$customerRef'});
    }
    GraphQLQueryNode query = new GraphQLQueryNode('OrderQuery', parentNode);
    query.fragments.add(OrderHeaderQueryFragment.getFragment());
    
    if (m_params.IncludeLines)
        query.fragments.add(OrderHeaderQueryFragment.getLineFragment());
    
    query.withVariable('count', 'Int = 10');
    query.withVariable('cursor', 'String = null');        
    query.withVariable('ref', '[String] = null');  
    query.withVariable('status', '[String] = null');
    
    if (m_params.CustomerId != null)
       query.withVariable('customerRef', 'String!');  
    
    return query;    
}

The code I've used to generate this renders the query like this (notice '$customerRef' is in double quotes):

query OrderQuery($count: Int = 10, $cursor: String = null, $ref: [String] = null, $status: [String] = null, $customerRef: String!)  {
  orders(first: $count, after: $cursor, ref: $ref, status: $status, customerLink: {ref:"$customerRef"}) {
    pageInfo {
      hasPreviousPage
      hasNextPage
    }
    edges {
      cursor
      node {
        id
        status
      }
    }
  }
}

Describe the solution you'd like

I'd like to be able to nest arguments in the query as my example shows at the top/

Describe alternatives you've considered

I've modifed the GraphQLArgument code locally to allow passing a nested GraphQLArgument to the withVariable() method. I added code to handle the GraphQLArgument type in the toString() method where it renders the key/value pair as desired.

Discussed in #33

GraphQLField revokeDrivePrevileges = new GraphQLField('revokeCoReader')
            .withArgument('brandId', 'BMW')
            .withArgument('carType', 'SUV')
            .withArgument('accountId', '12345768')
            .withArgument(
                'metadata',
                new Map<String, Object>{
                    'channel' => new GraphQLEnum(Constants.CHANNEL),
                    'authorType' => new GraphQLEnum(Constants.AUTHOR_TYPE),
                    'agentId' => '123456'
                }
            );

Summary

I am trying to implement a mutation that creates a token using an email and password combination in the variables. I am receiving this error: First error: Syntax Error GraphQL (1:37) Expected $, found @ in reference to the @ in the email being passed.

Steps To Reproduce:

1. Created the code using this structure:

` GraphQLField tokenCreateNode = new GraphQLField('tokenCreate')
// Point the argument to the variables
.withArgument('email', '$email')
.withArgument('password', '$password')
.withField('token')
.withField('refreshToken');

GraphQLMutation mutation = new GraphQLMutation('CreateToken', tokenCreateNode)
// Define variable for the mutation
.defineVariable('email', email)
.defineVariable('password', password);`

Expected result

Successful callout

Actual result

Getting syntax error

Summary

Short summary of what is going on or to provide context.

Steps To Reproduce:

1. This is step 1. Clicked the install in sandbox link form your readme
2. This is step 2. Clicked install for admins only, but al lit does is running and saying looking for admins and them error when it times out because the run time is took too long

Expected result

Expected it not to take so long to install and time out ..

Actual result

got an email that let me know the installation of the package failed
