Hello I got problem with parsing my date

                  .map((column) => {
                return column.column.dataType === "DATE" ? (
                  <TableCell key={column.id} align={column.align}>
                    {format(
                      new Date(parseFloat(column.value)),
                      dateFormat,
                      new Date()
                    )}
                    {console.log(parseFloat(column.value))}
                  </TableCell>

heres the code where I format my date.

import DateFnsUtils from "@date-io/date-fns";
import { MuiPickersUtilsProvider } from "@material-ui/pickers";

return (
<Provider store={store}>
  <MuiPickersUtilsProvider utils={DateFnsUtils}>
    <ApplicationContainer />
  </MuiPickersUtilsProvider>
</Provider>);

This is my App.js

still I get this error Format string contains an unescaped latin alphabet character g
