finally i found this error on my sentry server :

  />
  <CustomModal onRequestClose={this.handleClose} modalVisible={modalVisible}>
    <DatePicker

I know it's been 2 months and my answer may not help you, but it may help some future people facing this problem.

The problem is "This package only works with 'English' digits for numbers", Therefore you can't use any kind of localization to change Numbers into Persian or Arabic digits. you are forced to feed the app only 'English' digits.

I'm using some digit changer functions to change persian2english where I want to feed the component and english2persian where I want to show the numbers in Text or other places.

here the functions (I found them somewhere and don't have access to source, so I just copy the code) :

export const e2a = (s) => s.replace(/\d/g, (d) => "٠١٢٣٤٥٦٧٨٩"[d]);

export const p2e = (s) => s.replace(/[۰-۹]/g, (d) => "۰۱۲۳۴۵۶۷۸۹".indexOf(d));
export const a2e = (s) => s.replace(/[٠-٩]/g, (d) => "٠١٢٣٤٥٦٧٨٩".indexOf(d));

export const p2a = (s) =>
  s.replace(/[۰-۹]/g, (d) => "٠١٢٣٤٥٦٧٨٩"["۰۱۲۳۴۵۶۷۸۹".indexOf(d)]);
export const a2p = (s) =>
  s.replace(/[٠-٩]/g, (d) => "۰۱۲۳۴۵۶۷۸۹"["٠١٢٣٤٥٦٧٨٩".indexOf(d)]);
