# Antithesis Report 07.12.2023
Summary of the errors found running the initial devnet 12 images:
- Failed Block Import: Failed to import proposed blocks due to various reasons, including mismatching execution payloads and illegal state modifications.
- Validator Indices and Committee Information Issues: Encountered exceptions related to active validator indices, committee information derivation, and potential violations of slashing conditions probably do to a chain-reorg.
- Debug Log Reports: Several debug logs revealed breaches of protocol, corrupt inputs, internal errors like null pointer exceptions, and closure of deflators, all of which can jeopardize system stability and security.
