Faceted search using solr-node - node.js

Question

I am trying to search my documents indexed on solr 6.6.5 using facet search in node.js with the solr-node module. But when I add facet=on&facet.query=: I get an HTTP 400 response from solr-node.
var client = new SolrNode({
host: 'localhost',
port: '8983',
core: 'IRF18P4',
protocol: 'http',
debugLevel: 'ERROR' // log4js debug level paramter
});
var delhiCount = client.query.q('*:*&facet.query=city:delhi&facet=on');
// Search documents using strQuery
client.search(delhiCount, function (err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.response);
});
But if I try to open the same URL printed in my terminal, it works. Any idea on what could be going wrong here?

Your URL being printed in Output is Wrong.
http://localhost:8983/solr/IRF18P4/select?q=*%3A*%26facet%3Don%26facet.query%3Dcity%3Adelhi&wt=json
Above should look like,
http://localhost:8983/solr/IRF18P4/select?q=*:*&facet=on&facet.query=city:delhi&wt=json
And your code should be,
var delhiCount = client.query
.q('*:*')
.addParams({
facet: 'true',
facet.query: "city:delhi"
wt: 'json',
});
