Precompile error.. main runtime: panicked at 'Digest item must match that calculated,'

Question

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!

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
