From b688b0176e66539bf8ac400cad40c1867198603d Mon Sep 17 00:00:00 2001 From: hailin Date: Tue, 30 Dec 2025 19:16:38 -0800 Subject: [PATCH] fix(service-party-app): serialize BigInt to string for sessionStorage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BigInt cannot be serialized by JSON.stringify.
