我试图改变mui主题的原色，但是当我应用它的时候，我得到了各种各样的错误。

import { createTheme, ThemeProvider } from "@mui/system";
import "./App.css";
import IntegrationsPage from "./pages/integrations/IntegrationsPage";

function App() {

  const theme = createTheme({
    palette: {
      primary: {
        main: "#4B68FE",
      }
    }
  });

  return (
    <div className="App">
      <ThemeProvider theme={theme}>
        <IntegrationsPage/>
      </ThemeProvider>
    </div>
  );
}

export default App;

以下是错误。不设置主题时，错误不会出现。

我需要设置所有的主题值吗？如果我只想改变主颜色呢？
