Events passed in error log

Problem/Motivation

In error log I have continuously (every day) “page not found” of past events:
https://www.gmpe.it/calendar-field_data_evento/year/20220828
https://www.gmpe.it/evento/2021-10-02t133000
https://www.gmpe.it/calendar-field_data_evento/year/201005
……
but they are not present in the content because I deleted them.

Solutions?

Thank you
