# Error messages

When building a resource rule graph, the Side panel displays error messages if any are found in the graph, using the following icons:

- Check icon No errors found
- Circle Alert icon Error detected

If you click the Errors detected icon in the Side bar, the nodes with errors display with a red box and the error icon. If there are multiple errors, hover over the node to see the specific error or errors for that node.
