Couldn't prepare knowledge map

Atlas could not get usable text or rendered pages from the PDF.

1. Open the PDF and confirm that source processing finished.
2. Check whether the PDF pages and text are available in Atlas.
3. Return to the knowledge map after the source is ready.

If source processing failed, use Troubleshoot source processing.

Couldn't create or load knowledge map

• For Couldn't create knowledge map, use the retry control after the source or note is ready.
• For Couldn't load knowledge map, try loading the saved map again.

If the same message returns, keep the item name and exact error message for support.

A map edit is unsaved

The full knowledge map shows Unsaved when Atlas cannot store a canvas change and Offline when the browser has no connection.

1. Keep the map open.
2. Reconnect if the map shows Offline.
3. Make another small edit after the connection returns.
4. Wait for Saved.

Avoid reloading the page while the map is Unsaved.

Download is unavailable

Download remains unavailable while the map is generating or before the canvas is ready. Wait for the map to finish.

The semantic map is empty

Clear the field in the composer at the bottom of the map, or press Escape, to remove any search or classification. If a legend row has a hollow dot, that color is hidden. Select the row to show it again.

The map shows only sources and notes. Chats never appear on it. If the project has no processed sources or notes, add a source or write a note before returning to the map.

The semantic map does not render

Refresh the page and reopen the semantic map. If Atlas shows an error, record the project name, approximate time, browser, and visible message, then contact support.
