failed to insert new head to L2 execution engine

When running simple-taiko-node and restarting it, it starts showing this error and prover doesn't work anymore. The only way to fix it is to delete volumes and start again.

Possible cause is docker forcefully stopping it after 10 seconds

Since for A3 network, when we build a pending block's anchor tx, we need to query the "L1signalRoot" by an eth_getProof RPC query (now we have ~300 L2 pending blocks in avg), but a Sepolia geth's full node will only store last 128 blocks' state trie, so if a user's Sepolia provider only provides "Sepolia full node endpoint" but not "Sepolia archived node enpoint", u will get this error (missing trie node). And the solution is using a archived Sepolia node's endpoint.

I'm using Alchemy, don't they use archive node?

How do I determine whether an RPC node is a full node or an archive node?
