yaml.DEFAULT_SCHEMA.extend is not a function

I am stuck with a lambda error yaml.DEFAULT_SCHEMA.extend is not a function while running the below code.


class CustomYamlTag {
    constructor(type, data) {
        this.type = type;
        this.data = data;
    }
}



//Lambda handler

exports.handler = event => {
    logger.info('Event', event);
    const SCHEMA = yaml.DEFAULT_SCHEMA.extend(tags);
    let TemplateBody = yaml.load(fs.readFileSync('templates/TEMPLATEFILE.yml', 'utf8'), { schema: SCHEMA });
....

I tried const SCHEMA = yaml.Schema.extend(tags); and ended up with the error yaml.Schema.extend is not a function

Any suggestions on how to fix this or what I am doing wrong?

Thanks in advance.

The error was thrown as I was using js-yaml 3.9.0.

I upgraded from js-yaml 3.9.0 to js-yaml 4.0.0 version and this allowed me to use yaml.DEFAULT_SCHEMA.extend.

extend property was added to the package on versions after 4.0.0
