Parachains not producing blocks with polkadot release-v1.4.0

Question

I am running a local zombienent network with zombienet version 1.3.86

The config.toml file:

[settings]
timeout = 1000

[relaychain]
chain = "westend-local"
default_command = "./polkadot"

  [[relaychain.nodes]]
  name = "alice"
  ws_port = 9900
  validator = true

  [[relaychain.nodes]]
  name = "bob"
  validator = true

[[parachains]]
id = 2000
cumulus_based = true
chain = "asset-hub-westend-local"

  [[parachains.collators]]
  name = "charlie"
  validator = true
  command = "./bin/polkadot-parachain"
  ws_port = 9910
  args = ["--force-authoring"]

The relay chain is producing blocks, however, the parachain doesn't.

There seem to be no errors by looking at the zombienet log files.

Answer 1

as I mention in my comment using the latest version of zombienet will work with that config but you need to compile polkadot with fast-runtime to reduce the epoch time (parachains start to producing blocks after 2 epochs).

You can compile polkadot with fast-runtime with this command

cargo build --locked --profile testnet --features fast-runtime --bin polkadot --bin polkadot-prepare-worker --bin polkadot-execute-worker

Thanks!
