# Error Reference {% hint style="danger" %} ### THIS DOCUMENTATION IS NO LONGER USED Go to for the most current version of the documentation. {% endhint %} If there are errors with your sheet configuration, it will be prevented from saving with a message to explain why. Eventually this page will include a reference listing of common errors, but if you're unable to resolve an issue based on the error message output by the system, head to the #powered-by-the-apocalypse channel of the Foundry Virtual Tabletop Discord for more advice. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://asacolips.gitbook.io/pbta-system/error-reference.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
