Cyrillic url are handled incorrectly. You can see the log. You can see that in the log snippet
all Cyrillic parts of a URL, they have for example a cyrillic letter "с" or "я" cause the error and ignored from matomo.
The paths for example:
You can see that, if you open the log file with the notepad++ (format UTF8)
Tried tracking an url containing your examples locally and it worked correctly.
Might be an issue of database collation. Could you check which collation your database and the table
matomo_log_action has on your install?
The collation of the database (MariaDB) is utf8_general_ci, of the table matomo_log_action also utf8_general_ci. The database is auto created while matomo installation.
Were you able to reproduce the error?
I think that cannot be due to the collation of the database, because "Action name" is entered in the table "matomo_log_action" without any problems (even if the string contains the cyrillic letters "с" or "я"). But the "Action URL" cause the error as soon as the url contains cyrillic letters "с" or "я". I think the URL was previously converted to the wrong format (bevor the inserting in the database).
I use Matomo 3.13.4
Windows Server 2019
I am always available for additional information. Thanks.
Actually I was not able to reproduce when I send those chars in the URL. Are you able to find those requests to matomo.php in the access log? Maybe they are already sent malformed
