The error message is indicating that an undefined array key (index) 1 is being accessed in the file "ServeCommand.php" at line 309. This error is likely being caused by a failure to find a match using the regular expression defined in the variable $regex.
One possible solution would be to check the output of the preg_match function before accessing the index in the matches array. If there are no matches found, you can either return a default value or throw an exception to handle the error.
Let me give you an example so that you can understand better.
preg_match($regex, $line, $matches);
if (count($matches) < 2) {
throw new Exception("No match found for the given regular expression");
}
return Carbon::createFromFormat('D M d H:i:s Y', $matches[1]);
