Cannot access filter createFilter method

[codeana]

Hello,

I am writing a node js application and trying to create a jira filter using jira-connector api. However, I am not able to access createFilter method. Could somebody please elaborate me on how can I access the createFilter method to create a filter on jira.

Sample code:
const JiraClient = require("jira-connector");
const jira = new JiraClient({
host: "jira.abcd.com",
basic_auth: {
username: "xxxxx",
password: "xxxxxxxxx"
}
});
jira.filter.createFilter() // Unable to access the function here.

Please let me know.
Thank you!
