st.exception

Display an exception.

When accessing the app through localhost, in the lower-right corner of the exception, Streamlit displays links to Google and ChatGPT that are prefilled with the contents of the exception message.

Function signature[source]
st.exception(exception, width="stretch")
Parameters
exception (Exception)	The exception to display.
width (int or "stretch")	The desired width of the exception expressed in pixels. If this is `"stretch"` (default), Streamlit sets the width of the exception to match the width of the parent container. Otherwise, this must be an integer. If the specified width is greater than the width of the parent container, Streamlit sets the width of the exception to match the width of the parent container.
