Error starting Heimdall non-Validator node

Polygon Mainnet (PoS)

Hello, our node was fully operational until Aalborg Hardfork. After updating to the ver 1.0.1, node doesn’t start.
Error:

panic: Failed to process committed block (2:15DED8D79DF2F24D46482D313B656EA9DBBA78A58D4477315C082A2C0DE2C6D4): Wrong Block.Header.AppHash.

Maybe you switched heimdall version after hard fork, not before?

Yes, indeed, but after I’ve downloaded a snapshot and tried to start, but still getting this error. Even with empty data folder.

I’ve downloaded a fresh snapshot, initialized heimdall, heimdall started to sync but got this error:

most likely you need to specify the chain, they changed the default to a devnet so you’ll need to specify mumbai or mainnet in the --chain flag

    command:
      - heimdalld
      - start
      - --moniker=node
      - --chain=mainnet
      - --p2p.laddr=tcp://0.0.0.0:26656
      - --rpc.laddr=tcp://0.0.0.0:26657
      - --home=/var/lib/heimdall
      - --rest-server

Fixed a Heimdall node with a solution from here - Wrong Block.Header.AppHash. · Issue #1084 · maticnetwork/heimdall · GitHub
Moved a chain=mainnet to the heimdall-config.toml
