javax.servlet.ServletException: java.lang.NullPointerException

Jenkins JIRA | stephan stachurski | 4 months ago

    This is using Jenkins ver. 1.646, and BlazeMeter plugin 2.5. In my jenkins proxy configuration, I can set that and successfully reach http/https://a.blazemeter.com using "Validate Proxy". Although it looks like the proxy is configured correctly, when adding a blazemeter API key credential, "Test Blazemeter API Key" results in a NullPointerException. Here's the stack trace: {code} javax.servlet.ServletException: java.lang.NullPointerException at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:796) at
