 ## Archiver Errors
 
-- "No non-nullified L1 to L2 message found for message hash ${messageHash.toString()}" - happens when the L1 to L2 message doesn't exist or is "pending", when the user has sent a message on L1 via the Inbox contract but it has yet to be included in an L2 block by the sequencer - user has to wait for enough blocks to progress and for the archiver to sync the respective L2 block. You can get the sequencer to pick it up by doing 2 arbitrary transaction on L2 (eg. send DAI to yourself 2 times). This would give the sequencer a transaction to process and as a side effect it would consume 2 subtrees of new messages from the Inbox contract. 2 subtrees needs to be consumed and not just 1 because there is a 1 block lag to prevent the subtree from changing when the sequencer is proving.

 - "Block number mismatch: expected ${l2BlockNum} but got ${block.number}" - The archiver keeps track of the next expected L2 block number. It throws this error if it got a different one when trying to sync with the rollup contract's events on L1.
