Weird urls got created with Django + plotly

Hello everyone.

I am new to this forum (and plotly).
I tried to use plotly for data visualization on my website, but I immediately got a problem (though the charts were working fine).
I have asked for help on stacker overflow already, so to avoid duplicates I just post the link.

I want to underline that I am not using plotly anymore for this website, but I am still having problems with this urls that got created for the pages that existed when I used plotly, please have a look at this screenshot of my google search console:


The new pages of my website (after I uninstalled plotly don’t act like this, what is the problem here?

How can I get rid of all of these β€œweird” urls?

Thanks, any suggestion will be much appreciated,
Vittorio
