`IgxDateFormatterPipe` throws `TypeError: Cannot read properties of undefined (reading 'length')` when `format` is `undefined` after Angular 22.1 upgrade

[ivanvpetrov]

Description

Summary

After upgrading to Angular 22.1, BaseFormatter.formatDate() throws a TypeError when the format argument is undefined (i.e. not provided by the caller). This is a regression caused by a new validation call (assertValidDateFormatLength) introduced in Angular 22.1's formatDate().

• New method introductin:
  https://github.com/angular/angular/blame/main/packages/common/src/i18n/format_date.ts#L138

function assertValidDateFormatLength(format: string) {
  if (format.length > MAX_DATE_FORMAT_LENGTH) {  //.length throws an error
    throw new RuntimeError(
      RuntimeErrorCode.SUSPICIOUS_DATE_FORMAT,
      ngDevMode &&
        `Date format is too long. Exceeded maximum length of ${MAX_DATE_FORMAT_LENGTH} characters.`,
    );
  }
}
