I am running a local testnet of a 2-validator-node polkadot Relay Chain (release-v0.9.27) and I am trying to connect a parachain-template to it (v0.9.27), with custom keys. The Relay Chain is working as intended, producing and finalizing blocks.

When I connect the parachain (have tried with 1 collator and 2 collators) to the Relay Chain, the parachain tries to import the first block but never does it, and all I get is Collation wasn't advertised to any validator. That procedure continues for a while (5-10mins) and then I get the following errors:

[Parachain] Block import error: State Database error: Too many sibling blocks inserted
[Parachain] Error with block built on 0xda79ce961787fcc5e5a97a19cd2a03695b30ee1791fb94a5045cf58f164951d0: Import failed: State Database error: Too many sibling blocks inserted
[Parachain] Failed to collect collation info. error=Application(UnknownBlock("Header was not found in the database: 0x89acf273da66c70e14bd8c5daac0f82235522d15a61ef0a06d925dcf08a3340d"))

I have checked everything in these sanity checklists (How can I get my parachain to produce blocks? (sanity checklist) and Our parachain doesn't produce blocks [checklist]) and everything should work.

I have also tried increasing the Validator count of the Relay Chain to 3 and I am still getting the same results.

  • Can you please give more information on how you run the nodes? Do you use docker? Or anything else? You could try running with --discover-local.

    I am using github.com/CherryNetwork/polkadot (branch = cherry) and github.com/CherryNetwork/evm-parachain/tree/main/runtime (branch = main). I am not using a docker. I just build and run. The steps I am doing in more details are the following: 1. Spin up the first validator Relay node 2. Spin up the second validator Relay node 3. Insert their keys through a curl command 4. Register the ParaId (2000) 5. Spin the parachain collator node 6. Insert their keys through a curl command 7. Use parasSudoWrapper to Initialize the parachain

    I have also tried running the v0.9.27 and v0.9.28 polkadot and rococo Relay. I got the exact same results. When I run my custom branches with --alice and --bob everything works btw. It is kinda strange.

    I tried adding the --discover-local tag and it didn't work unfortunately. Thank you @bkchr. I will try tomorrow the Zombienet and will let you know @Bruno. Thank you as well!

    @Bruno Sorry for my super late reply. Was working on some other stuff. I tried Zombienet but I couldn't really reproduce the issue. I was expecting Zombienet to work because it uses --alice and --bob. I am still pretty confused of this issue... it doesn't make sense.

The question is answered here. Apparently there was a problem inserting the keys. After following all the steps of the solution, my parachain could produce and finalize blocks.
