The actions you've taken seem correct, but there might be a bug causing the issue. First, ensure that the endpoint URL and token (if necessary) are correctly set in the settings. If the problem persists, check the idea.log file for any errors related to Agent. You can filter the log by the keyword Agent. Additionally, enable all level logs for tabby and check for the log entry INFO - #com.tabbyml.intellijtabby.agent.AgentService - Agent init done. If you don't find this, it indicates that the tabby-agent.js script might be throwing errors. For troubleshooting, try running your built tabby-agent.js script with node ./tabby_agent.js and send it an init request to see if the response is correct. If the script starts successfully and responds correctly to the init request, the issue might be elsewhere.
