I was adding a new precompile function to my parachain,

then when I ran my parachain and invoked one of the precompile functions, I got this error from one of the polkadot validators: Relaychain Collation wasn't advertised to any validator

and that validator went from connecting to 2 peers(the other validator and the parachain) to 1 peer(the other validator).

and this error showed up from my parachain collator:

ERROR main runtime: panicked at 'Digest item must match that calculated.' [Parachain] Could not find the header of the genesis block in the database! runtime::storage: Corrupted state at [29, 186, 24, 76, 175, 197, 232, 114, 222, 94, 248, 240, 95, 69, 38, 7, 232, 157, 0, 204, 183, 181, 2, 22, 12, 248, 168, 34, 221, 252, 65, 168, 174, 167, 89, 124, 78, 203, 37, 115, 239, 230, 87, 126, 236, 129, 58, 120, 13, 109, 47, 202, 237, 47, 44, 205, 92, 29, 92, 134, 70, 132, 144, 242, 170, 254, 236, 139, 124, 177, 74, 245, 18, 205, 248, 199, 152, 1, 131, 163]

Need to build a new WASM again following the tutorial https://docs.substrate.io/tutorials/connect-other-chains/connect-a-local-parachain/

./parachain-collator build-spec \ --disable-default-bootnode > rococo-local-parachain-plain.json \ && ./parachain-collator build-spec --chain rococo-local-parachain-plain.json \ --raw --disable-default-bootnode > parachain-raw.json \ && ./parachain-collator export-genesis-wasm \ --chain parachain-raw.json > para-wasm \ && ./parachain-collator export-genesis-state \ --chain parachain-raw.json > para-genesis
