Laravel HandleExceptions class cuts the log message short

I am working on legacy code with Laravel 5.2. There are cases where I have a runtime error and it gets handled and logged by Laravel's HandleException class. This gets logged in my log file like this:

[2019-10-10 08:59:48] production.ERROR: #0 /var/www/project/lib/folder1/folder2/folder3/file.php(293): Illuminate\Foundation\Bootstrap\HandleExceptions->handleError(8, 'Undefined prope...', '/var/www/projec...', 293, Array)

Under this message I can see the full call stack. But as you can see, the messages are shrinked and cut with ..., so I cannot read the full error message. Do you know why? Can I somehow configure Laravel to show the full message?
