An error occurred when using jsencrypt in a lower version of Chrome

[wrh8214158]

chrome version: 17
jsencrypt version: 3.3.2

I have tried installing all versions of jsencrypt, but still reported an error.

use like this:

export const rsaEncrypt = (val: Record<string, unknown> | unknown[] | string | number = '') => {
  const PUBLIC_KEY = `sdwdwadwadwdsasdwadwdwadawdawdwadwad`;
  const encrypt = new JSEncrypt();
  encrypt.setPublicKey(PUBLIC_KEY);
  const value =
    typeof val === 'object'
      ? JSON.stringify(val)
      : ['string', 'number'].includes(typeof val)
      ? String(val)
      : '';
  return encrypt.encrypt(value);
};

error:
