Reject the zero address before sending the transaction.
When the history is empty, ethers.utils.isAddress accepts ethers.constants.AddressZero, and L1Sequencer.setFirstSequencer then reverts with invalid address instead of returning invalid firstSequencerAddress.
Proposed fix
- if (!ethers.utils.isAddress(firstSequencer)) {
+ if (
+ !ethers.utils.isAddress(firstSequencer) ||
+ firstSequencer.toLowerCase() === ethers.constants.AddressZero
+ ) {
return `invalid firstSequencerAddress: ${firstSequencer}`

Reject the zero address before calling setFirstSequencer. ethers.utils.isAddress accepts ethers.constants.AddressZero, so a zero firstSequencerAddress reaches L1Sequencer.setFirstSequencer. The contract rejects it with "invalid address", which causes the deployment task to stop before registering the first sequencer.
