NextJ, supabase 400 POST error on inserting values

Im working in a realtime chat application with NextJS and Supabase and recently (without any changes to the code) my application is refusing to post the new messages and im trying to figure it out what im doing wrong but i cant.

I Tried to go back to the first version of the code that used to work perfectly and i still got the same error which make me think that something happened with supabase not with the code

Here is how im doing my DB connection:

const SUPA_KEY = '...myKey...'
const SUPA_URL = 'https://myurl.supabase.co'
const dbSupaInteraction = createClient(SUPA_URL, SUPA_KEY)

The insert function:

const [message, setMessage] = React.useState('')
const [messageList, setMessageList] = React.useState([])

function handleNewMessage(newMessage) {
    const message= {
        id: messageList.length + 1,
        de: loggedUser,
        texto: newMessage,
        created_at: (new Date()).toLocaleDateString()
    }
    console.log(message)
    dbSupaInteraction.from('mesHis').insert([message])
    .then(({data}) {
            console.log('Return handleNewMessage:::: ' + JSON.stringify(data));
            console.log('Message to be sent:::: ' + JSON.stringify(mensagem));
        })

    setMensagem('');

}
<TextField
    placeholder="Insert new message here..."
    value={message}
    type="textarea"
    styleSheet={{
       ...
     }}
       onChange={(event) => {
          const value= event.target.value
          setMesssage(value)
        }}
        onKeyPress={(event) => {
          if (event.key === 'Enter') {
             event.preventDefault();
             handleNewMessage(message);
            }
           }
          }
        />

The error:
Printscreen of console error

Im posting here as my last resource cause i already spent a whole week in this problem and cant figure it out 🙁
