/api/v1/chat.postMessage stop working in 7.4.0

[fidojones]

Description:

After upgrade from 7.3.1 to 7.4.0 the /api/v1/chat.postMessage stop working with this message:

{"success":false,"error":"must NOT have additional properties\n must NOT have additional properties\n must match exactly one schema in oneOf [invalid-params]","errorType":"invalid-params"}

We downgraded to 7.3.1, and all continue working again.

Steps to reproduce:

Sending the exact same params with curl (has been working the same, in all previous versions)

curl --request POST --url https://DOMAIN/api/v1/chat.postMessage --header 'X-Auth-Token: AUTH_TOKEN' --header 'X-User-Id: USER_ID' --header 'accept: application/json' --header 'content-type: application/json' --data '{ "alias": "BOT_ALIAS", "channel": "#CHANNEL_NAME", "roomId": "ROOM_ID", "text": "bip"}'
