As well as what @hMsats wrote, you can also fix this by adding deprecatedrpc=fees to your bitcoin.conf file and then restarting Bitcoin Core.

The same kind of thing happened with this other issue: https://github.com/chris-belcher/electrum-personal-server/issues/247

I found a work around for now:

In /home/user/.local/lib/python3.8/site-packages/electrumpersonalserver/server/mempoolhistogram.py

I changed line 108:

mempool_tx = self.rpc.call("getmempoolentry", [txid])

into

mempool_tx = self.rpc.call("getmempoolentry -deprecatedrpc=fees", [txid])

and EPS was working again. This was changed in version 23 of Bitcoin Core

- - The top-level fee fields `fee`, `modifiedfee`, `ancestorfees` and `descendantfees`
  returned by RPCs `getmempoolentry`,`getrawmempool(verbose=true)`,
  `getmempoolancestors(verbose=true)` and `getmempooldescendants(verbose=true)`
  are deprecated and will be removed in the next major version (use
  `-deprecated=fees` if needed in this version).
