Newsletter w:mex queries receive bad request nodes on most endpoints

[Thomas-Pellan]

Hello,

While trying to query a channel info, join or leave a channel the following node is sent back by whatsapp :

{"data":null,"errors":[{"message":"Bad Request","path":[],"extensions":{"error_code":400,"severity":"CRITICAL","is_retryable":false}}]}

My test code :

//Extracted from sockerhandler
private CompletableFuture<Node> sendQuery(String id, Jid to, String method, String category,
                                        Map<String, Object> metadata, Node... body) throws CobaltApiNotFoundException {
        var attributes = Attributes.ofNullable(metadata)
                .put("xmlns", category, Objects::nonNull)
                .put("id", id, Objects::nonNull)
                .put("to", to)
                .put("type", method)
                .toMap();
        return 
                api.sendNode(Node.of("iq", attributes, body));
    }     

//Extracted from sockethandler
private CompletableFuture<Node> sendQuery(String method, String category, Node... body) {
        return sendQuery(null, JidServer.WHATSAPP.toJid(), method, category, null, body);
    }

public String test() {
var key = new QueryNewsletterRequest.Input(Jid.of(jidStr), "JID", NewsletterViewerRole.GUEST);
        var request = new QueryNewsletterRequest(new QueryNewsletterRequest.Variable(key, true, true, true));

        CompletableFuture<Optional<String>> future = sendQuery("get", "w:mex", Node.of("query",
                Map.of("query_id", "6620195908089573"),
                        Json.writeValueAsBytes(request)))
                .thenApply(result -> result.findChild("result")
                .flatMap(Node::contentAsString));

        return future.join().orElse(null);
}   

This seems to happen on joinNewsletter/leaveNewsletter/queryNewsletterSubscriber/queryNewsletter so most of the w:mex message types.

I tried to change the queryids with some coming from WhiskeySockets's Baileys but with no success. joinNewsletter/leaveNewsletter seems to not work for them too, but get channel meta data does.

version tested : 0.0.7

Update on this after further testing :

queryNewsletter : the reason for the bad request seems to be the boolean fetchFullImage in QueryNewsletterRequest.Variable, when switching it to false the request responds normally

working eg :

var key = new QueryNewsletterRequest.Input(Jid.of(jidStr), "JID", NewsletterViewerRole.GUEST);
var request = new QueryNewsletterRequest(new QueryNewsletterRequest
                .Variable(key, true, false, true));

CompletableFuture<Node> future = sendQuery("get", "w:mex", Node.of("query",
                        Map.of("query_id", "6620195908089573"),
                        Json.writeValueAsBytes(request)));

return future.join();

join/leave newsletter : seems to work when testing with a phone to validate the subscription, error was in my code sorry.
