The problem in catching exceptions

[demortx]

The problem occurs when you create a global variable with an object of any class, except that it handles the variables only to an array, but when it receives an exception in the global variable, it throws an internal error.

#0 [internal function]: CodeIgniter\Debug\Exceptions->shutdownHandler()

#0 [internal function]: CodeIgniter\Debug\Exceptions->shutdownHandler()

It is easy to see that first the exception is normally worked out, and then it is covered by a mistake from the exception itself, and in this case the error is only visible in the log

Sorry for Google translator from Russian

it looks like the ResponseTrait::format / ResponseTrait::respond failed to handle the response correctly

could you provide/post the array you use in the response function call - its pretty hard to understand the callstack without any data

[lonnieezell]

Yes, please provide additional details on how to recreate. I'm having a hard time following this one.

I can't fully reproduce the bug, but here’s another one that got

$options = [
'base_uri' => 'you.com', // need returned error: 403 Forbidden
'timeout' => 1
];
$client = \Config\Services::curlrequest($options);
$response = $client->get('api/config'); <

and we see an error here again

as you can see the first error returns us -> 403 Forbidden
but for what reason does the whole script fly away to the exception, I understand it is clear

This is indeed hard to follow.
If I interpret the above correctly, then we have a stack trace from a curl request exception that was not caught - so totally expected. Then it looks like the debugger tried to handle the re-thrown exception and interpret the error message as JSON, but it wasn't in JSON format.
Is this a configuration problem? a bug in Kint? Is this even a CodeIgniter bug?

[jim-parry]

There is a todo item a few entries down in the issues list that suggests that CURL needs some helpers, eg. for JSON. Is this evidence of such a lack?

CRITICAL - 2018-09-28 20:33:03 --> Undefined variable: is_install
#0 /var/www/web.ru/application/Modules/Globals/Module/func.php(209)

Is the $is_install defined?

Try:

$options = [
'base_uri' => 'you.com', // need returned error: 403 Forbidden
'timeout' => 1,
'http_errors' => false, // This avoids an exception thrown if the HTTP code is is greater than or equal to 400 
];
$client = \Config\Services::curlrequest($options);

[jim-parry]

It looks like this is happening inside application/Modules/Globals/Module/func.php and/or application/API/v1/System/Upload.php, and I can't follow how this is a CodeIgniter bug.
Not getting further details from OP, or enough to replicate.

[pixobit]

Managed to reproduce this issue. Was uploading an image with jquery.dm-uploader.min.js, and trying to do some image manipulation, but when I got this error:
{title: "ErrorException", type: "ErrorException", code: 500, message: "getimagesize(): Read error!",…} code: 500 file: "C:\xampp\htdocs\project\app\Controllers\File.php" line: 85 message: "getimagesize(): Read error!" title: "ErrorException" trace: [{function: "errorHandler", class: "CodeIgniter\Debug\Exceptions", type: "->",…},…] type: "ErrorException"

Then I was basically getting the same response as the OP.

Note: I managed to get the real exception by printing in in the FormatException.php file
