Lemmy is written in rust, that's a java error so the issue lies with the app you're using not Lemmy itself (maybe)

The cause is a 502 from lemmy.

Jerboa's handling of that error is also terrible but that's another issue.

Memmy doesn’t do well with it either.

Of course it doesn’t bode well for the instance itself that it’s throwing so many…but it’s unclear if that’s an operator problem or a code base problem.

It could also just be a server load issue.

Lemmy.world, the community the instance is hosted on, has been having a few issues between the 0.18.1 update, and the amount of users on the platform.

Jerboa or just in the browser. Honestly though most people's issues are likely to be because they joined a huge instance which is falling over due to load. Consider making a new account on a smaller instance.

I’m finding issues with communities not loading posts, comments or general sync issues.

Lemmy's Rust code uses an ORM called Diesel that masks the SQL statements and you really have to watch the PostgreSQL server independently to verify that the SQL isn't doing wild things like loading thousands of records when you only needed 3. Just today people are finally sharing some information out of the big servers (lemmy.world) as to what PostgreSQL side says is actually happening. Hopefully the biggest mistakes are going to get cleaned up quickly.

Afaik this is not an error from Lemmy but from nginx, which is not able to relay the request to Lemmy and therefore returns a 502 bad gateway response. Imo this just means the servers are over capacity, so most likely a scaling/infrastructure issue.

I had a quick read of the code and it looks pretty solid to me. Not the most "enterprise" code imaginable, but definitely no code smell or quick hacking job.

I think it's both, actually. Lemmy is often giving html where json is expected, and Jerboa isn't handling the error well.

usernotfound 20 points 3 years ago

🤔 The server spits out html when it cannot reach the backend. So one could argue it's a configuration issue because the admin didn't provide enough capacity / didn't set up a proper generic json error for backend failures.

FWIW, Liftoff doesn't handle these super gracefully either.

At any rate I think it's kinda awesome that we get to witness these kinds of infancy problems.

No, this is a lemmy issue. The API specification specifies a JSON response, and the server randomly provides HTML, this is a bug in the server.

lemmy does not return 502 error codes because 502 means "bad gateway" and lemmy is not acting as a gateway, nginx is. An nginx sends the html. All apps should check the status code for codes like this one that don't come from apps.

I would say Lemmy issue. This is probably a default 502 internal sever error response (which I've been getting repeatedly from lemmy.world). Jerboa (I don't use it btw) is only trying to parse the expected json response. Yes the app could handle the error more gracefully but if Lemmy didn't respond with an error jerboa wouldn't need to.

When you get a 502 error, that's not coming from lemmy, it's coming from nginx. If you're saying that nginx should send any error data along with the status in json if the accept headers require it, that's a task for nginx but it wouldn't happen in this case anyway since the json wouldn't be what they were expecting anyway. The app should be handling non success responses better is the point being made here.
