Missing entry for fork "cancun" in blobSchedule

Trying to build the docker conteiners, an error occur in eth-pos-devnet-geth-genesis-1:
"Fatal: Failed to write genesis block: invalid chain configuration: missing entry for fork "cancun" in blobSchedule"

Few days ago there was new realse of ethereum/client-go which propably change something in interface of genesis.json.

Setting in docker-compose ethereum/client-go:release-1.14 instead of ethereum/client-go:latest for both images that uses it work as temporary work-around for me.

I could fix that above error when I put the below setting in genesis.json. As far as I read the main.go file of go-ethereum, this object seems to be fine. But I don't understand what is the proper number to assign to each parameter.

"blobSchedule": {
			"cancun": {
				"target": 6,
				"max": 6,
				"baseFeeUpdateFraction": 6
			}
		}
