Type 'string[] | undefined' is not assignable to type 'string | undefined'

I am new to typescript. I am facing some while declaring Props in typescript as follows:

Types of property 'd' are incompatible.
Type 'string[] | undefined' is not assignable to type 'string | undefined'.

I have one xyzProps which contains some sting type and one is string[] as given below:

const d1: string[] = [];

type xyzProps = {
  a: string;
  b: string;
  c: string;
  d: typeof d1;
};

When I am trying to use the above propes as follows then it gives an error

export type abcPageProps = RouteComponentProps<Partial<xyzProps>> & ReduxProps;

Any idea why it gives me this error OR any solution for it.

can you try

type xyzProps = {
   a: string;
   b: string;
   c: string;
   d: string[];
};

export type abcPageProps = RouteComponentProps<xyzProps> & ReduxProps;
