TypeScript: Object is possibly 'undefined'

const FormInput: FC<IFormInputProps> = ({ name, label, ...otherProps }) => {

  const {
    control,
    formState: { errors },
  } = useFormContext();

  return (
    <Controller control={control} defaultValue='' name={name} render={({ field }) => (
        <FormControl>
          <Typography>{label}</Typography>
          <Input {...field} error={!!errors[name]} {...otherProps} />
          <FormHelperText error={!!errors[name]}>
            {errors[name] ? errors[name].message : ''}
          </FormHelperText>
        </FormControl>
      )}
    />
  )
}

export default FormInput

TypeScript ругается на вывод сообщения {errors[name] ? errors[name].message : ''}

Как победить?
