Gatling Jenkins plugin stopped to render charts in reports. I guess charts are generated by JavaScript so the problems seems to stem form the the error I found in Chrome Web browser:
Blocked script execution in ‘http://myjenkins:7080/job/run-authn-per…get/gatling/results/generatetokenoncevalidatemany-1453691533709/index.html’ because the document’s frame is sandboxed and the ‘allow-scripts’ permission is not set.
I will continue to analyze the root cause and possible fixes, but any suggestions are welcome.
