ERROR located in src/app/account/phone-login/phone-login.component.ts(288,53): error TS2339: Property 'split' is not a valid property for type 'string | Int32Array'. Property 'split' cannot be found on type 'Int32Array'.
This seems to be a peculiar issue that arose following the update of the angular version.
let hash = (Md5.hashStr(this.account.password)).split('');
hash[5] = this.account.password.charAt(0);
hash[10] = this.account.password.charAt(1);
hash[15] = this.account.password.charAt(2);
let cryptoPwd = hash.join('');
