getGroupChatHistory returns 404 (/api/group/history) while getGroupInfo works — endpoint moved?

[saloprj]

Version

zca-js@2.1.2 (latest published; also verified against main — identical source).

Summary

api.getGroupChatHistory(groupId, count) fails with ZaloApiError: Request failed with status code 404 for a valid group, while other group-service calls on the same session and same service host succeed.

Reproduction

const api = await zalo.login({ cookie, imei, userAgent }); // session OK
api.getOwnId();                       // ✅ returns own uid
await api.getAllGroups();             // ✅ group present in gridVerMap
await api.getGroupInfo(groupId);      // ✅ valid group, enableMsgHistory: 1, real members
await api.getGroupChatHistory(groupId, 50); // ❌ ZaloApiError 404

• The groupId is confirmed correct (it's a key in getAllGroups().gridVerMap, and getGroupInfo returns its full info with name, creatorId, members).
• The group is not empty — it has messages.
• enableMsgHistory is 1 in the group settings.

Likely cause

Both calls target the same host (api.zpwServiceMap.group[0]), but:

• getGroupInfo → /api/group/getmg-v2 — works
• getGroupChatHistory → /api/group/history — 404

The working sibling is versioned (getmg-v2); the failing one is the unversioned /api/group/history. It looks like Zalo moved/retired the old group-history path server-side (possibly to a versioned endpoint), so the current getGroupChatHistory implementation 404s.

Request

Could the group-history endpoint URL / params be updated to whatever the current Zalo Web client uses? Happy to help capture the current request shape if useful.
