Catching "Your app is having trouble loading the ..." warning in Python

Andrei_Volkau · February 18, 2021, 1:56pm

Is there any way to catch “Your app is having trouble loading the …” warning in Python? I would like to handle it instead of showing a message like the following one.

The message seems to be generated in Typescript.

github.com

streamlit/streamlit/blob/49770d050e44296718ab36a3914a5c9d8330001b/frontend/src/components/widgets/CustomComponent/ComponentInstance.tsx#L289


    disabled: this.props.disabled,
  })
}
private renderError = (error: Error): ReactNode => {
  return <ErrorElement name={error.name} message={error.message} />
}
private renderComponentReadyTimeoutWarning = (): ReactNode => {
  const message =
    `Your app is having trouble loading the **${this.props.element.componentName}** component. ` +
    `\n\n(The app is attempting to load the component from **${this.props.element.url}**, and hasn't ` +
    `received its **"${ComponentMessageType.COMPONENT_READY}"** message.)` +
    "\n- If this is a development build, have you started the dev server?" +
    "\n- If this is a release build, have you compiled the frontend?" +
    `\n\nFor more troubleshooting help, please see the [Streamlit Component docs](${COMPONENT_DEVELOPER_URL}) ` +
    `or visit our [forums](${COMMUNITY_URL}).`
  return (
    <Alert width={this.props.width} body={message} kind={Kind.WARNING} />
  )
