Exception in WS read thread: RSV1 bit of a frame is set unexpectedly

[freya022]

General Troubleshooting

• I have checked for similar issues on the Issue-tracker.
• I have checked for PRs that might already address this issue.

Version of JDA

5.0.0-beta.18

Expected Behaviour

Handle the frame gracefully I guess?

Code Example for Reproduction Steps

N/A

Code for JDABuilder or DefaultShardManagerBuilder used

JDABuilder.createLight(token)
            .enableIntents(GatewayIntent.MESSAGE_CONTENT)
            .setActivity(Activity.customStatus("I need more bullets"))
            .setEventManager(/* */)
            .build()

BEFORE REPORTING A SIMILAR ERROR

Please update to the JDA snapshot #2663 (comment) and include the WebSocket trace with the error

[MinnDevelopment]

The latest master commit added a new trace information to further investigate this issue, please let me know when you encounter the error including that trace detail.

I tried this and it works fine in my environment
I used JDK 17 and dependencies {implementation("net.dv8tion:JDA:5.0.0-beta.18")} and run by InteliJ
This is my test code and result

import net.dv8tion.jda.api.JDABuilder;
import net.dv8tion.jda.api.entities.Activity;
import net.dv8tion.jda.api.requests.GatewayIntent;

public class BotApplication {

    public static void main(String[] args) {
        JDABuilder.createLight(Bot.token) // my test token
            .enableIntents(GatewayIntent.MESSAGE_CONTENT)
            .setActivity(Activity.customStatus("I need more bullets"))
            .setEventManager(null)
            .build();
    }
}

This is not an issue on startup, it happens at random times, days after the bot started, multiple people have reported this issue, I've created this issue for tracking purpose, so it can also be linked when a fix is available

Oh, I see. I didn't know that. Thank you for telling me. :)

Please send the exception with the WS trace, like duncte123 sent

I don't think I have WS trace enabled or how to retrieve it. I have the stacktrace that is the same as the OP

I have updated my POM, will see if I get it again. Slaynash/Lumbot@d30becd

This issue has been escalated to cloudflare. Apparently, the web socket is receiving an http response body instead of a web socket frame. The specific bit happens to be set when the frame starts with HTTP/1.1 502 Bad Gateway Server.
