Associate records (N:N relationship) via JavaScript

My requirement is to create an association between 2 entity records where there is an N:N relationship between those 2 entities. I built the query with the REST builder. But when I execute it gives the error “Bad Request”. When I examined the response using F12 developer tools the details error is like this:

“Invalid role specified for entity 'new_contract'in relationship 'new_cancellationreason_contract.Referencing”.

My relationship name, entity names and GUIDs are double checked and correct. Any idea what this error is??

This is my query which was generated by the REST builder:

var association = {

    "@odata.id": Xrm.Page.context.getClientUrl() + "/api/data/v8.2/new_cancellationreasons(6abb5393-b53e-e711-80d4-005056b44566)"

};

var req = new XMLHttpRequest();

req.open("POST", Xrm.Page.context.getClientUrl() + "/api/data/v8.2/new_contracts(104A85B0-6DA9-E611-B581-005056B44BD9)/new_cancellationreason_contract/$ref", false);

req.setRequestHeader("Accept", "application/json");

req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

req.setRequestHeader("OData-MaxVersion", "4.0");

req.setRequestHeader("OData-Version", "4.0");

req.onreadystatechange = function() {

    if (this.readyState === 4) {

        req.onreadystatechange = null;

        if (this.status === 204 || this.status === 1223) {

            //Success - No Return Data - Do Something

        } else {

            Xrm.Utility.alertDialog(this.statusText);

        }

    }

};

req.send(JSON.stringify(association));

var association = { "@odata.id": Xrm.Page.context.getClientUrl() + "/api/data/v8.2/new_contracts(104A85B0-6DA9-E611-B581-005056B44BD9)" }; var req = new XMLHttpRequest(); req.open("POST", Xrm.Page.context.getClientUrl() + "/api/data/v8.2/new_cancellationreasons(6abb5393-b53e-e711-80d4-005056b44566)/new_cancellationreason_contract/$ref", false);
