To me, it seems too obvious that Israel must have known that Israel intelligence and Government must have known this attack was coming. Here are things that seems to make it impossible for them to have been ignorant:

Former IDF soldiers say they know whenever a bird lands on the Gaza border wall. Hamas could somehow use bulldozers to make huge tunnels under the wall. 2 .Over 1000 Hamas fighters were aware of this plan. For each fighter that was aware, there must have been another half dozen friends or family members that must have known also. Mossad has no intelligence on this? Nobody said anything?

It is well know that Israel has some of the world's best digital snooping capabilities in the world. This must be largely focused on members of Hamas. There were no intercepted text messages or voice calls from thousands of Hamas members?

Hamas attacked Israel in the same way and places as before, just at a larger scale. Israel wouldn't immediately recognize the patterns of getting ready again?

Hamas would have been able to bring over 5000 rockets into a small area undetected.

We are to believe that the Iron Dome conveniently went down the night of the attack, not unlike the cameras in Epstien's prison cell.

Egypt warned Israel a few days before this attack that Hamas was planning something.

Many warned that the 6 billion Biden gave to Iran would be used for terror Israel government had no interest in tracking this?

Those are a few of the obvious reasons I could think of. What can you add?
