1 Answer 1


as I see, you are trying to run relay-messages-rialto-to-millau.sh but before that you need to run also relay-rialto-to-millau.sh and relay-millau-to-rialto.sh,


  • just relays messages

relay-rialto-to-millau.sh / relay-millau-to-rialto.sh:

  • initialize bridge pallets (see the error BridgePalletIsNotInitialized)
  • relays finality (headers)
  • sequence I have executed:1.running both nodes(rialto and millau), 2.running relays. 3.running the relay-messages but still i am getting the same error

  • could you, please, add here logs from "2.running relays." ? Nov 15, 2022 at 11:10
  • yes, really, there was problem with scripts (wrong account used), please, update your git branch origin/master, there is a fix for that Nov 17, 2022 at 0:34
  • ~/parity-bridges-common$ ./scripts/send-message-from-rialto-millau.sh transfer error: Found argument '--target-signer' which wasn't expected, or isn't valid in this context USAGE: substrate-relay send-message <bridge> --source-host <source-host> --source-port <source-port>

  • sorry for unsatisfactory answer and troubles, please update repo, right now just this should work ./scripts/send-message-from-rialto-millau.sh remark (send some Trap message), inside that script, arguments remark/transfer is wrong, there should be raw <some-encoded-call>, like raw 020419ac is Trap(..) call, but honestly, I see 020419ac in code base, but I dont know how was this generated, trying to find out also, we dont really use this script, and they surely needs to be updated: github.com/paritytech/parity-bridges-common/issues/1406 Nov 21, 2022 at 16:41
