I am setting up a Jira configuration from my Jenkins server. After entering all necessary parameters (Site Name, Webhook URL, Secret), I successfully tested the configuration and received a message saying, "Successfully validated site credentials." However, when I clicked the 'Save' button, I encountered the following error:

"Cannot invoke 'com.atlassian.jira.cloud.jenkins.config.JiraCloudPluginConfig.configure(org.kohsuke.stapler.StaplerRequest, net.sf.json.JSONObject)' because 'this.config' is null."

An image is attached. Does anyone have any idea why this might have happened?
