Error: Attempting to access the 'main' property of an undefined object - React dilemma

For my React webpage, I decided to create a theme using createMuiTheme from material-ui, and here is the palette I defined:

palette: {
    primary: {
      main: "#333333"
    },
    secondary: {
      main: "#727171"
    },
    background: {
    paper: "#f8f3f0",
    default: "#f8f3f0"
    },
    accent: {
      main: "#80d6d1"
    }
}

When attempting to use the accent color for some text, I typically do it like this:

const useStyles = makeStyles(theme => ({
  content: {
    backgroundColor: theme.palette.background.default,
    minHeight: "90vh",
    color: theme.palette.background.main
  }
}));

However, I encountered an error message:

TypeError: Cannot read property 'main' of undefined

  71 |     minHeight: "90vh",
> 72 |     color: theme.palette.accent.main
  73 |   }
  74 | }));

Do you have any insights on what might be causing this issue?

Answer №1

Ensure to import the component from '@material-ui/core' and NOT from '@material-ui/styles' into the App.js file.

I mistakenly did the same thing before, but now everything is functioning flawlessly!

Thank you!
