SOLVED: Additional HTTP/GET request is generated automatically

Hello
I am getting a strange behavior with a blank application.

When that application is called either by GET or POST, an additional request is generated by GET.
For example:
successful request: https://app.domain.com/blank_01/
and a request https://app.domain.com/blank_01/blank_01.php is generated at the same time.
Both are included in the nginx logs.

Also in the case that the request has some parameters, when the second request is generated, they are not included.

Does anyone know what could be happening?

Regards.

The problem came from the index.html file of the application
when invoking it there is window.location=“blank_01.php” that generated a GET redirection to the application when it was invoked by POST.

More info:
The index.html was created by SC at some point.
The file has never been generated again but at some point SC generated it.

I haven’t looked at this for a while, however all my cron jobs always call app/app.php for this reason. Other than cron jobs I haven’t come across this issue anywhere else.
