1. If it is just a react project and the DVA framework is introduced, an onerror attribute will be passed in when calling the DVA method

const app = dva({
	onError(err) {
		// error
		console.log(err);
	},
});

2. If you are using the UMI framework, you cannot find the place where the DVA is called. Create a new app.js file in the SRC directory and write the following contents

export const dva = {
  config: {
    onError(e) {
      e.preventDefault();
      console.error(e.message);
    },
  },
};
