We all have them, learn how to cope with them Here's a general list of troubleshooting steps if you're getting errors. The log files are VERY important since Lucee's error doesn't always contain the information you need. You must crack open your Lucee logs to get the actual error out. * Look in the `out` and `err` logs for information. These are usually found in the servlet container's log directory. For instance, if you're using Tomcat, look in Tomcat's `log` directory. Messages are often logged there that never make it up to the CFML engine. * Always scroll to the bottom of Java stack traces to look for a **caused by** section, which is the original error. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://ortuspdf.ortusbooks.com/essentials/debugging.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
