Hi trying to embed a webchat into my nextJS app. it displays fine and everything but i cant send messages from the site. it keeps saying

Uncaught (in promise) 
Object { message: "must have required property 'body'" }
​
message: "must have required property 'body'"
​
<prototype>: Object { … }

i keep getting a 400 on that and the bot errors out and restarts a convo. i think the injection script is sending an incorrect api call? i followed the docs here https://botpress.com/docs/webchat/get-started/quick-start https://cdn.discordapp.com/attachments/1462218039494967358/1462218040107208997/Screenshot_2026-01-17_at_3.51.55_PM.png?ex=697b3beb&is=6979ea6b&hm=87529dc7c89bfdbeb13000b6e5c03d96f143f470336061aef27db92b47b88196&
