175-175: Enhanced error handling in file operations.The addition of detailed error messages when opening, marshaling, and writing to a file enhances the traceability of errors. This is a solid improvement in error handling practices.
Also applies to: 189-189, 194-194
Line range hint
34-34: Robust error handling throughout the command setup.The command setup includes comprehensive error handling at every step, from initializing node validator files to verifying the deposit message. This thorough approach ensures that any issues are caught and handled appropriately, aligning with the PR's objectives.
Also applies to: 50-50, 58-58, 66-66, 74-74, 82-82, 90-90, 98-98, 106-106, 114-114, 122-122, 130-130, 138-138, 146-146, 154-154, 162-162

149-149: Proper error handling in directory creation.The function
makeOutputFilepathhandles potential errors during directory creation effectively, providing clear error messages if the operation fails. This is consistent with best practices in error handling.Also applies to: 151-151
197-197: Correct use of dependency injection ingetBLSSigner.The function
getBLSSignereffectively uses dependency injection to retrieve the BLS signer, handling errors appropriately. This implementation is clean and follows best practices.
[APROVED]Also applies to: 199-199

25-37: Centralized error declarations are well-defined and clear.The error declarations are specific and appropriately named, which enhances maintainability and readability. This approach also makes it easier to handle errors consistently across the

175-175: Enhanced error handling with contextual information.The updated error handling in
writeDepositToFileuses the centralized error variables effectively, providing more context by including theoutputDocumentanddepositMessagein the error messages. This approach aids in debugging and traceability.Also applies to: 189-189, 194-194
178-185: Consider logging file closure errors independently.The current logic only sets the file closure error if no other error has occurred. It might be beneficial to log this error independently to ensure that file closure issues are always captured, which could be critical for diagnosing issues in production environments.

Enhance error message for marshaling failure.
The error message here could also benefit from more details about the data being marshaled, which could help in debugging.

Improve error message for write failures.
Similar to the open and marshal errors, including the file path in the error message when a write fails can aid in troubleshooting.

Improve error message for better traceability.
The error message for failing to open a file is good, but it could include the file path for better traceability.
