KeyError: 'fee' when starting EPS

[Arns]

My setup used to work just fine a few months back around April. I just tried to boot EPS up (with Bitcoin Core, Electrum Wallet) and I get the following error:

KeyError: 'fee'

The element "fee" has been deprecated from the json object returned by getmempoolentry. See https://developer.bitcoin.org/reference/rpc/getmempoolentry.html

A new object "fees" contains the element "base" which should replace the previous "fee"

fees = mempool_tx["fees"]
fee_rate = 1e8*fees["base"] // mempool_tx["vsize"]

Running into this error as well. Has this been changed in a new version?
