This function replaces [system.gui.errorBox](versioned_docs/version-8.1/appendix/scripting-functions/system-gui/system-gui-errorBox.md). Any scripts containing Vision Client scoped functions that were replaced with system.vision syntax will still work to maintain backwards compatibility.
:::

This function is used in **Python Scripting**.
