Backendless Version (3.x / 6.x, Online / Managed / Pro )

Codeless Logic

Client SDK (REST / Android / Objective-C / Swift / JS )

Application ID

91B1BBBC-51BA-F6F3-FFC0-EDF5487CA600

Expected Behavior

Please describe the expected behavior of the issue, starting from the first action.

1. I’m making a request to the following endpoint “https://api.backendless.com/91B1BBBC-51BA-F6F3-FFC0-EDF5487CA600/AEDD5C9F-4F55-40D2-9A59-AAE1A7DADD32/services/ResumeScore/check”
2. I should get a proper JSON response with various data.

Actual Behavior

Please provide a description of what actually happens, working from the same starting point.

Be descriptive: “it doesn’t work” does not describe what the behavior actually is – instead, say “the request returns a 400 error with message XXX”. Copy and paste your logs, and include any URLs.

Hello @Arnold_N

I managed to reproduce only in 5% of attempts, tell me, do you get an error for each request or do you periodically?

I created an internal ticket (BKNDLSS-26257).

[Arnold_N]

It’s happening with every request we make. Also this only started happening yesterday, this API has been working perfectly for months. It also serves a live product and that’s why the urgency. Is there anything you deployed yesterday that could be causing this issue.

Hello @Arnold_N

We just investigated the issue and found that your logic makes a few requests to external services and it appears, some of that requests fail with the following error: ECONNREFUSED xxx.xxx.xx.x:443 (I masked the real IP address), I would recommend you to add a couple “Print” (with some log message) blocks in order to figure out what exactly request fails.

You can see that if you open the REAL-TIME LOGGING

Also in the log, you can see that the API Service starts/ends in normal mode without any internal error

Please let us know if we can assist you with anything else.
Regards, Vlad
