Unable to declare multiple custom named properties TypeScript MUI v5 Palette

I am trying to setup many custom attributes to keep things semantically easy to update in the future. However I am having issues with having more than just one custom property in MUI v5

Ts Error

TS2717: Subsequent property declarations must have the same type. Property 'background' must be of type 'TypeBackground', but here has type 'PaletteColor'.

palette.ts

export const palette = {
  primary: {
    light: '#6D6B8C',
    main: '#6514DD',
    dark: '#6D6B8C',
  },
  secondary: {
    main: '#6D6B8C',
  },
  error: {
    main: '#bd4646',
  },
  background: {
    main: '#fff',
    paper: '#F5F5F5',
  },
  border: {
    main: '#DADAE1',
    primary: '#DADAE1',
  },
  text: {
    primary: '#6D6B8C',
    secondary: '#000',
  },
}


declare module '@mui/material/styles' {
  interface Palette {
    border: Palette['primary']
    background: Palette['primary']
  }

  // allow configuration using `createTheme`
  interface PaletteOptions {
    border?: PaletteOptions['primary']
    background?: PaletteOptions['primary']
  }
}
