K6 Invalid character '<' looking for beginning of value

Hi Team,
I am trying POC to send k6 logs to grafana cloud and folloling below writeup

when i run without company VPN i can see log streaming to cloud but when i enable VPN i start getting below error

ERRO[0001] invalid character ‘<’ looking for beginning of value

please help me to resolve issue

I think you need to use your corporate proxy for access to internet over VPN, so just use right env variables for that, eg

HTTP_PROXY=http://corp-proxy:port k6 run script.js
HTTPS_PROXY=https://corp-proxy:port k6 run script.js
