X509: certificate signed by unknown authority CMD K6.io

I am presently using a nice tool to perform performance testing (load) for a project via a VPN. I am using K6 and SOAPUI. run the same tool using both tools just to compare results. K6 is a Javascript library that gathers robust configurable metrics, and likewise SOAPUI. The challenge is that SOAPUI works smoothly while K6 always hit a certificate issue. Since SOAPUI works fine I believe the problem is either certificate issue with my system or K6.io. I’m yet to figure out what the real problem is.

The main reason why I like k6 is because of the robust reporting tools it integrates with like InfluxDB and Grafana. It is because I have to generate graphical reports for the test.

Error from k6.io CMD

script: AccountClosure.js
