503 with no reason

when I'm trying to make POST to my app endpoint, I'm getting 503 I put in body fields to update in DB, like id and amounts but when code comes to DB interactions, Railway send me 503 cuz Railway doesn't allow my app to log into console, I'm doing it in response body I've wraped all db calls with try-catch, but I doesn't get any response from them, but 503 from Railway

Solution:

it was just 0xC0000005

please read this https://docs.railway.app/troubleshoot/fixing-common-errors

Satan1cOP•12mo ago

no... application is responding but not in all cases

Brody•12mo ago

ah, then make sure you are using https

Satan1cOP•12mo ago

and I'm already using 0.0.0.0:PORT)

Brody•12mo ago

i mean use https when making api calls

Satan1cOP•12mo ago

oh, yep I do

Brody•12mo ago

then your app is sending malformed responses back or you are sending malformed requests to railway

hm... I'll add some data: 503(Railway response) body:

{
    "label": "5",
    "withdraw_amount": "1"
}

{
    "label": "5",
    "withdraw_amount": "1"
}

200(any my responses) bodies:

{
    "label": "5",
    "withdraw_amount": "0" // any less than 1
}

{
    "label": "5",
}

{
    "withdraw_amount": "5",
}

{ }

// or no body

{
    "label": "5",
    "withdraw_amount": "0" // any less than 1
}

{
    "label": "5",
}

{
    "withdraw_amount": "5",
}

{ }

// or no body

all invalid body variants are responds normally, cuz of my checks but if body is valid... it must find user in DB and create or update it's record but... for some reason when it comes to DB interactions, Railway sending me 503 first of all I was guessing that there throws some error on DB call but, after I've wrapped all DB calls in try-catch, I'm still getting 503 I can't tell is it again some trouble cuz of docker/linux but I can't do request on my app, if I'll run it locally in docker, without it all is great

cuz Railway doesn't allow my app to log into console

maybe if it was possible to do logs, it'll be much easier, but, I can't see any log on website

Brody•12mo ago

why arent you using a proper database client to enter data into your database?

Satan1cOP•12mo ago

that's for payment service webhook they send a big json, but atleast for now, I'm interested only in that two fields

Brody•12mo ago

what do you see when you open your deploy logs?

Satan1cOP•12mo ago

Nothing But when deploy removed, I see there all logs that my app was sending from very beginning

Brody•12mo ago

are you using a dockerfile?

Satan1cOP•12mo ago

As I remember from earlier trys, docker is the only option for C++, so yep, I use Dockerfile

Brody•12mo ago

what logging library are you using?

Satan1cOP•12mo ago

I use logs that included in drogon framework Bu I also tried cout and fpritf with stdout specification *drogon version from vcpkg

Brody•12mo ago

please make sure you are not buffering your logs railway uses a line based scanner, so if you are buffering logs, the line scanner will not see any lines

Satan1cOP•12mo ago

Hm... cout and other use streams for printing... So maybe that's the case, I'll look up for alternatives spdlog works just fine but... I'm still cant get any error logs

[02:59:54] info app init
[03:02:07] info before find
[03:02:07] info before casted
[03:02:07] info before filter
[03:02:07] info before doc

[02:59:54] info app init
[03:02:07] info before find
[03:02:07] info before casted
[03:02:07] info before filter
[03:02:07] info before doc

spdlog::get("console")->info("before casted");
auto casted = static_cast<int64_t>(id);

spdlog::get("console")->info("before filter");
auto filter = make_document(kvp("_id", casted));

spdlog::get("console")->info("before doc");
try    {
    const auto doc = m_collection.find_one(filter.view());
    spdlog::get("console")->info("before return");
    return doc.has_value();
} catch (const mongocxx::query_exception& err) {
    spdlog::get("stderr")->error("mongocxx::query_exception");
    spdlog::get("stderr")->error(err.what());
} catch (...) {
    spdlog::get("stderr")->error("unknown error");
}

return false;

spdlog::get("console")->info("before casted");
auto casted = static_cast<int64_t>(id);

spdlog::get("console")->info("before filter");
auto filter = make_document(kvp("_id", casted));

spdlog::get("console")->info("before doc");
try    {
    const auto doc = m_collection.find_one(filter.view());
    spdlog::get("console")->info("before return");
    return doc.has_value();
} catch (const mongocxx::query_exception& err) {
    spdlog::get("stderr")->error("mongocxx::query_exception");
    spdlog::get("stderr")->error(err.what());
} catch (...) {
    spdlog::get("stderr")->error("unknown error");
}

return false;

the worse that I can't trigger that on local to debug if there no errors... may be DB call doesn't sent... or maybe it self triggering Railway to do 503 response ?
