Multiple spaces in the Regular Expression form are replaced with one space in the Configuration section
A RE isn't reflected to the format key in the auto-generated configuration code as it is when a RE has multiple spaces like below.
Here is my regular expression. In my case, there are 2 spaces right after the regular expression for the time parameter. Those characters are omitted to one space in the Configuration section.
^(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}.\d{3})Z (?<log_level>\w+) \[(?<module>\w+)\] (?<message>.*)
e.g: https://fluentular.herokuapp.com/parse?regexp=%5E%28%3F%3Ctime%3E%5Cd%7B4%7D-%5Cd%7B2%7D-%5Cd%7B2%7D+%5Cd%7B2%7D%3A%5Cd%7B2%7D%3A%5Cd%7B2%7D.%5Cd%7B3%7D%29Z++%28%3F%3Clog_level%3E%5Cw%2B%29+%5C%5B%28%3F%3Cmodule%3E%5Cw%2B%29%5C%5D+%28%3F%3Cmessage%3E.*%29&input=2022-12-06+03%3A26%3A14.885Z++info+%5BMyApplication%5D+Starting+logging++-+%28MyApplication.java%3A100%29&time_format=%25Y-%25m-%25d+%25H%3A%25M%3A%25S.%25L
I guess this issue is related to html rendering or is a CSS side issue. The fluentd configuration is rendered with HTML tags. Because of it, multiple spaces are replaced with one space character.
