I throw error when get a api error and catch that by event 'unhandledrejection' on window. But in a react application, there is a dev error tips panel as shown. How can i disable it, i don't need it.

  • react is warning you that promise error in your code is not handled. It says `User` does not exist, so what you are trying to access is currently not exist. You have to show the `fetch` code for more clarity. Besides you should not ignore errors like this if you want the site to work properly – wyfy Aug 20 '20 at 14:05

    Error is expecte, and i will handle it on window 'unhandledrejection' event. But even though i listened the event and prevent the event on window. The error panel is still on display . – Spray Lee Aug 21 '20 at 02:30
  • I would also love to have a solution for this since i use an sdk which involves a small portion of code that is triggering an exception which is not handeled and catching it does still show the Unhandled rejection panel :/ – Mssm Apr 08 '21 at 17:10

You can use react-app-rewired to tweak CRA config https://github.com/timarney/react-app-rewired

Here is your config-overrides.js file

module.exports = (config) => {
  const refreshPlugin = config.plugins.find((plugin) => plugin?.constructor?.name === 'ReactRefreshPlugin')

  if (refreshPlugin) {
    refreshPlugin.options.overlay = false
  }

  return config
}
