level config is not working on SplunkLogger splunk-logging JS package

[PacoPeralta]

Hello Splunk team!
I'm having an issue setting the level parameter on the configuration object for SplunkLogger constructor on splunk-logging JS package version "^0.10.1".
This is my code:

const config = {
    token: `${process.env.SPLUNK_TOKEN}`,
    url: `${process.env.SPLUNK_HOST}`,
    level: "error"
};

const splunkLogger = new SplunkLogger(config);

It doesn’t matter which level I set, it always sending all the logs severities. 

Could you please help me on this?

Thanks in advance!
