Error Trying to access array offset on value of type null at


I have nextcloud installed again on a docker with qnap with the latest version 22.2.0 and with all the settings where it indicates that “All controls have passed”

The problem is that in the registry I get this error:

Error: Trying to access array offset on value of type null at /var/www/html/apps/logreader/lib/Controller/LogController.php#95

  1. /var/www/html/apps/logreader/lib/Controller/LogController.php - line 95: OC\Log\ErrorHandler::onError(2, “Trying to a … l”, “/var/www/ht … p”, 95)

And all the results in google lead to sites with no solution.

Can anyone tell me what I could look at with this error? I have solved several but this one I do not know what I can do.
