[NET-673] [Alert Ok2jmG] ink-sepolia_No_Dumper_Data

[elina-chertova]

Automated fix proposal for alert Ok2jmG.

• Alert: ink-sepolia_No_Dumper_Data
• Base branch: open-beta
• Investigation: /root/alert/incident-agent/agent-system/data/investigations/Ok2jmG
• Report: /root/alert/incident-agent/agent-system/data/investigations/Ok2jmG/report.html

Reviewer quick view

• Scope: 2 file(s) in evm

• Root cause (agent): not explicitly captured

• Summary: ink-sepolia_No_Dumper_Data (Ok2jmG) — Root Cause Confirmed

  Root cause: dump-ink-sepolia-0 is in CrashLoopBackOff (124 restarts, exit 1) because OP Stack
  deposit transactions (type 0x7e) legitimately omit nonce, but rpc-data.ts declares nonce:
  SMALL_QTY as mandatory — causing DataValidationError on every block containing a 0x7e tx.

  Fix — 2 files in evm/evm-rpc/src/ (squid-sdk, open-beta):

  1. rpc-data.ts (1 line): nonce: SMALL_QTY → nonce: option(SMALL_QTY)
  2. verification.ts (15 sites): BigInt(tx.nonce) → BigInt(assertNotNull(tx.nonce, 'tx.nonce is
     missing')) — prevents TypeScript compile failure now that nonce is optional

  Operator action required: After PR merges and new evm-dump image is built, update ink-sepolia.yaml
  image tag from 87fd334 to the new digest.

  Verdict: accept — implementer patch is correct and complete; root cause fully explained by direct
  log + code evidence.

Fix metadata

• Fix class: rca_fix
• Confidence: high
• Evidence basis: logs, code
• Falsification: If rpc-data.ts line 221 already reads nonce: option(SMALL_QTY) in
• Follow-up: Merge PR → build new evm-dump image → update ink-sepolia.yaml image

Risk & rollout

• Suggested rollout: canary / one-network-first, then broader rollout after signal is stable.
• Rollback: revert this PR (or restore previous config values/files) if the incident signal worsens.

Reproduction status

Incident behavior was reproduced or corroborated strongly enough for a non-hypothesis fix proposal.

Validation checklist

• Verify the original incident signal improves (logs/metrics/alerts) after deploy.
• Verify no regression on sibling networks/providers/services touched by this change.
• Confirm queue / delivery pipeline status returns to expected steady state.

Changed files

• evm/evm-rpc/src/rpc-data.ts
• evm/evm-rpc/src/verification.ts
