In order to suggest you a quality solution, we shall usually ask you to provide the details mentioned below first. Including them into your topic right away helps us to start investigating your issue much faster.

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

Online

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

.net

Application ID

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.

Starting this morning, many requests that have been fine for the past year or more are suddenly returning error 400. Doesn’t seem to matter the type of request, from basic data retrieval to logins.

It is intermittent, sometimes the requests go through but over 50% of the time all requests are failing application wide.

here is an example log / call stack

Hello @Experimental_Design

In the response body from the server there should be a message and code, could you please provide them?

Regards, Vlad

Backendless BackendlessFault. Code: Internal client exception, Message: The remote server returned an error: (400) Bad Request.

vladimir-upirov · November 17, 2021, 6:33pm

according to your API Calls analytics for the past 30 days I can see there are errors only for specific APIs login/find/findById, so I assume it depends on input parameters

Also, I do not see that 50% requests are failed, I would say only
for Login it’s around 2.5%
for Data it’s less than 1%

Experimental_Design · November 17, 2021, 6:35pm

That makes sense. The past 30 days have been fine. It’s just starting this morning that we started seeing a large number of failures.

Backendless BackendlessFault. Code: Internal client exception, Message: The remote server returned an error: (400) Bad Request.

no, the code should be a Number and the message should describe the error with details, for instance if you send an invalid whereClause the server returns (400) Bad Request, but in the response we can see what exactly was wrong:

vladimir-upirov · November 17, 2021, 6:41pm

let’s try to reproduce the error with Login API

do you have the input parameters (login/password)? can you try to login using our REST Console (in the Data service) or some other service (Postman/etc)?

Experimental_Design · November 17, 2021, 6:43pm

Backendless BackendlessFault. Code: Internal client exception, Message: The remote server returned an error: (400) Bad Request.

That was printed with the following line of code.
Debug.Log(exception.ToString() + “Code:” + fault.FaultCode + “Message:” + fault.Message);

That is what I’m seeing in in code and message.

vladimir-upirov · November 17, 2021, 6:44pm

here is the today’s analytics, seems like there no many errors

vladimir-upirov · November 17, 2021, 6:46pm

in order to fix a problem we need to reproduce it first

Experimental_Design · November 17, 2021, 6:48pm

That seems like incorrect logging.

I’m seeing at least 10 or so fails with every user log in as the application loads ups and makes a number of requests at startup.

Experimental_Design · November 17, 2021, 6:49pm

Can you test with the .net library? Other users in the slack are also mention the same with the .net api.

vladimir-upirov · November 17, 2021, 6:52pm

Alright, we will check the Login API with the .Net SDK and notify you here about any result

vladimir-upirov · November 17, 2021, 6:53pm

what version of the SDK do you use?

Experimental_Design · November 17, 2021, 6:56pm

I’m not sure. Is there a place I can check?
We first started using Backendless in late 2019-ish, I think.
I have not updated the sdk since.

Experimental_Design · November 17, 2021, 7:05pm

Looks like it is BackendlessSDK-UnityPackage-5.1.0 was what I initially imported. But I also remember a year or more ago there was an issue we resolved over slack and Mark Piller sent a single dll to swap out.

parley-burnett · November 17, 2021, 7:46pm

This is from my analytics showing about 50% fail rate on the logins. Also using .net.

vladimir-upirov · November 17, 2021, 7:53pm

Hi @parley-burnett

Ok, do you have the same in your log?

parley-burnett · November 17, 2021, 8:00pm

Here’s a copy-paste from real-time logging. Does this help?

vladimir-upirov · November 17, 2021, 8:02pm

yes, thanks

Does the Error: The Company Id is empty at individual.create error come from your custom Business Logic?

What’s your AppId?
