Exceptions produce an empty object in the log

When the system logs an exception (either thrown, or caught and manually logged), the exception data is empty in the database.

What I'm using

Laravel: 9.x PHP: 8.1

Expected Behavior

Logging an exception will generate a log record in the database that includes data from the exception.

Observed Behavior

Logging an exception will generate a log record in the database that includes an empty object for the exception

Here is the output from a thrown exception after being recorded in the database.

39,ERROR,400,test,'{"exception": {}}',[],2022-12-25 19:12:33

Possible Resolution Options

Locally, I tested out two methods to resolution, both of which involved extending the DatabaseHandler class to do them.

Call the __toString() function from the exception object. This generates output similar to what is found in the log files.
This is what I ended up doing because having the data formatted like this was most useful to me: create a new array and add the message and stack trace data to that array.

[
    'message' => $exception->getMessage(),
    'trace' => $exception->getTrace(),
 ]

Replacing the exception object with the above will generate a log record that looks like this:

40,ERROR,400,Test Log,'{"exception": {"message": "test", "trace": [{"file": "/srv/vendor/laravel/framework/src/Illuminate/Routing/Controller.php", "line": 54, "type": "->", "class": "App\\Http\\Controllers\\HomeController", "function": "index"}, {"file": "/srv/vendor/laravel/framework/src/Illuminate/Routing/ControllerDispatcher.php", "line": 43, "type": "->", "class": "Illuminate\\Routing\\Controller", "function": "callAction"}, ...]}}',[],2022-12-25 19:24:22

Here is the full function I modified:

    protected function write( array $record ): void
    {
        $exception = null;
        if ( isset( $record[ 'context' ][ 'exception' ] ) ) {
            $exception = $record[ 'context' ][ 'exception' ];
        }

        if ( $exception instanceof Throwable ) {
            //If I was calling $exception->__toString(), I'd do that here as well
            $record[ 'context' ][ 'exception' ] = [
                'message' => $exception->getMessage(),
                'trace' => $exception->getTrace()
            ];
        }

        LogMessage::create( [
            'level' => $record[ 'level' ],
            'level_name' => $record[ 'level_name' ],
            'message' => $record[ 'message' ],
            'logged_at' => $record[ 'datetime' ],
            'context' => $record[ 'context' ],
            'extra' => $record[ 'extra' ],
        ] );
    }
