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

[–] Atemu@lemmy.ml 59 points 2 years ago (1 children)

The cause is a 502 from lemmy.

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

[–] 4am@lemmy.world 7 points 2 years ago (1 children)

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.

[–] T156@lemmy.world 6 points 2 years ago (1 children)

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.

[–] Marxine@lemmy.world 8 points 2 years ago (1 children)

Mostly the user count at this point, although things have become more stable the last few hours

[–] dukk@programming.dev 1 points 2 years ago

Yeah, I’ve only experienced this issue when dealing with Lemmy.world. Building my own client, and I get the same issue all the time.

[–] Binderfullofpizza@lemmy.world 2 points 2 years ago (9 children)

Is there a good Lenny app because so far wefwef hasn’t been great for me.

[–] LeylaaLovee@lemmy.fmhy.ml 9 points 2 years ago (1 children)

Liftoff is the best I've found so far. Waiting for Sync to come though

[–] kras@lemmy.world 5 points 2 years ago (1 children)

Same. RIP sync, long live sync!

[–] klyde@lemmy.world 1 points 2 years ago

Hopefully it doesn't take long. These other apps aren't bad but they aren't great either.

[–] yads@lemmy.world 7 points 2 years ago

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.

[–] foxrumor@lemmy.world 6 points 2 years ago

Wefwef has been the best for me so far. I'm a previous Boost for Reddit user, so I'm still waiting for their official Lemmy release and then I'll switch.

[–] uthredii@programming.dev 2 points 2 years ago

I am quite liking liftoff. It has a slightly different layout to wefwef and you can customize it a bit if you don't like the default colours.

[–] brettrick@infosec.exchange 1 points 2 years ago (1 children)

@Binderfullofpizza In my opinion, Memmy is the best native app at the moment (for iOS).

[–] Binderfullofpizza@lemmy.world 1 points 2 years ago

Thanks I’ll give that a shot.

[–] balls_expert@lemmy.blahaj.zone 1 points 2 years ago

Thunder but features aren't all there

[–] dukk@programming.dev 1 points 2 years ago

What’s so bad with wefwef? I’m using it righty now and enjoying it.

(Also, Memmy is another great Apollo-based app.)

[–] _thisdot@infosec.pub 1 points 2 years ago (1 children)

Can you explain why? Are you using wefwef on Android?

[–] Binderfullofpizza@lemmy.world 2 points 2 years ago (3 children)

I’m using it on iOS and don’t get me wrong the app looks beautiful. I’m finding issues with communities not loading posts, comments or general sync issues. I have an issue where trying to reply to a comment would overlay the comments over the textfield.

[–] RoundSparrow@lemmy.ml 6 points 2 years ago

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.

[–] wason@lemmy.world 3 points 2 years ago (1 children)

That might be a server issue. Lemmy.world is still having performance issues and just like the picture in this post we are all seeing many errors often.

[–] Binderfullofpizza@lemmy.world 2 points 2 years ago

I appreciate the explanation.

[–] Distributed@lemmy.ml 1 points 2 years ago (1 children)

That sounds like a server issue. Try a smaller server

[–] Binderfullofpizza@lemmy.world 1 points 2 years ago (1 children)

Can I change servers without changing my account?

[–] Distributed@lemmy.ml 2 points 2 years ago

At this time, no. This is a limitation on lemmy's side though

I've seen this more times than my own family

[–] csm10495@sh.itjust.works 14 points 2 years ago* (last edited 2 years ago) (1 children)

You know at least it printed an error. I hate when things silently swallow errors.

I'm looking at you, Python programmers:

try:
   <100 lines of nonsense>
except:
   pass
[–] rimorso@feddit.it 11 points 2 years ago (1 children)

We are not savages now we use

with suppress(Exception):
    > 100 lines nonsense

[–] Exatron@lemmy.world 13 points 2 years ago

Value of type java.lang.String cannot be converted to JSONObject

[–] shrugal@lemmy.world 11 points 2 years ago* (last edited 2 years ago) (1 children)

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.

[–] KD_14@lemmy.world 1 points 2 years ago

I read a couple PRs and it seems like the are rejecting the more hacky stuff.

[–] ggnoredo@lemm.ee 4 points 2 years ago (2 children)

that's Jerboa issue but probably because It received something from the server that it shouldn't

[–] Atemu@lemmy.ml 5 points 2 years ago (1 children)

No, the server gave a 502 instead of a JSON and Jerboa doesn't handle that gracefully.

[–] KD_14@lemmy.world 0 points 2 years ago (1 children)

Seems like the 4 apps I use all have the same issue though which makes me wonder if it's something in Lemmy causing the issue (not the apps).

[–] Atemu@lemmy.ml 7 points 2 years ago* (last edited 2 years ago)

Well, Lemmy shouldn't 502 in the first place. That's the root cause. The apps should handle that gracefully though, especially given how commonly Lemmy throws a 502.

[–] Achyu@lemmy.sdf.org 1 points 2 years ago (8 children)

Is it a lemmy issue or a jerboa issue?

[–] buda@lemmy.ml 9 points 2 years ago (3 children)

Serious Answer: This is a Jerboa issue. Lemmy is written in Rust. The error message is a Java error which is what native Android apps use.

[–] Serinus@lemmy.ml 4 points 2 years ago (4 children)

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

[–] usernotfound@lemmy.ml 4 points 2 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.

If it's Jerboa/Android app issue, why do I get JSON errors using Lemmy on my desktop PC with Firefox? Forgive me if this is a dumb question, I have very little programming knowledge.

[–] nothacking@discuss.tchncs.de 1 points 2 years ago

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. I agree that Jebora should retry in the case of a network failure (timeout, 4xx staus codes...) but it should not have to retry in a case of a server that is not folowing the standard.
