Chatbot hang in establishing connexion with customer service

Chatbot hang in establishing connexion with customer service

Hi,

When a user try to converse in the chatbot, the bot hang trying to establish a connection. 


Here are the errors in the console : 

POST https://salesiq.zohopublic.eu/visitor/v2/notariel/conversations 400 (Bad Request)

And also this error :

{
    "error": {
        "code": 1015,
        "param": "cvuid",
        "message": "Either the inputstream is invalid or absent"
    }
}

I don't understand how to debug this, here is the script used to call the bot:

 <script>window.$zoho = window.$zoho || {};
    $zoho.salesiq = $zoho.salesiq || {
        ready: function () {
            $zoho.salesiq.floatbutton.position("right");
            $zoho.salesiq.visitor.email("{{ auth()?->user()?->email }}");
            $zoho.salesiq.visitor.name("{{ auth()?->user()?->name  . ' ' . auth()?->user()?->last_name}}");
            $zoho.salesiq.visitor.id("{{ base64_encode(auth()?->user()?->email . ':' .  auth()?->user()?->id) }}");
        }
    }</script>
<script id="zsiqscript"
        src="https://salesiq.zohopublic.eu/widget?wc=[redacted]"
        defer></script>
