Local [Polkadot + Statemine] testnet with polkadot-launch - substrate

Question

I want to deploy a local Polkadot Testnet via polkadot-launch.
I built the executables from:
polkadot: v0.9.9-1
cumulus: statemine_v3
This is the config.json:
{
"relaychain": {
"bin": "./bin/polkadot",
"chain": "rococo-local",
"nodes": [
{
"name": "alice",
"wsPort": 9944,
"port": 30444
},
{
"name": "bob",
"wsPort": 9955,
"port": 30555
},
{
"name": "charlie",
"wsPort": 9966,
"port": 30666
},
{
"name": "dave",
"wsPort": 9977,
"port": 30777
}
],
"genesis": {
"runtime": {
"runtime_genesis_config": {
"configuration": {
"config": {
"validation_upgrade_frequency": 1,
"validation_upgrade_delay": 1
}
}
}
}
}
},
"parachains": [
{
"bin": "./bin/polkadot-collator",
"id": "200",
"balance": "1000000000000000000000",
"nodes": [
{
"wsPort": 9988,
"port": 31200,
"name": "alice",
"flags": ["--force-authoring", "--", "--execution=wasm"]
}
]
},
{
"bin": "./bin/polkadot-collator",
"id": "300",
"balance": "1000000000000000000000",
"nodes": [
{
"wsPort": 9999,
"port": 31300,
"name": "alice",
"flags": ["--force-authoring", "--", "--execution=wasm"]
}
]
}
],
"simpleParachains": [
{
"bin": "./bin/adder-collator",
"id": "400",
"port": "31400",
"name": "alice",
"balance": "1000000000000000000000"
}
],
"hrmpChannels": [
{
"sender": 200,
"recipient": 300,
"maxCapacity": 8,
"maxMessageSize": 512
}
],
"types": {},
"finalization": false
}
When I call polkadot-launch, all alice, bob, charlieanddave` have ok logs:

But 9988.log seems weird:
$ tail -f 9988.log
error: The argument '--force-authoring' was provided more than once, but cannot be used multiple times
USAGE:
polkadot-collator --alice --collator --offchain-worker <ENABLED> --force-authoring --in-peers <COUNT> --max-parallel-downloads <COUNT> --node-key-type <TYPE> --out-peers <COUNT> --parachain-id <parachain-id> --pool-kbytes <COUNT> --pool-limit <COUNT> --port <PORT> --rpc-methods <METHOD SET> --state-cache-size <Bytes> --sync <SYNC_MODE> --tmp --tracing-receiver <RECEIVER> --wasm-execution <METHOD> --ws-port <PORT>
For more information try --help
So I guess I'm only running a Relay Chain?
Collators for Cumulus/Statemine chains 200 and 300 are dead?
What's wrong with my setup?

Answer 1

Polkadot launch is handing over that argument by default now (because it was almost always needed). So just delete "--force-authoring", and it should all work.
