14. Added error logging for commitment flag failure in ProsopoDatabase class in mongo.ts
15. Added error logging for error in populateStep() function in populateDatabase.ts

Suggestions

1. In dependencies.ts, line 15, suggest using a more descriptive variable name.
2. Add comments to explain complex logic.
3. Consider using a logger library instead of console.error.

Bugs

1. Line 47 in an unspecified file: The condition if (typeof this.cause != ZodError && this.cause?.message && this.cause.message.length > MAX_ERROR_LENGTH) should be if (typeof this.cause !== 'undefined' && !(this.cause instanceof ZodError) && this.cause?.message && this.cause.message.length > MAX_ERROR_LENGTH).
2. Line 68 in an unspecified file: super(isError ? (error.message as TranslationKey) : error) should be super(isError ? (error.message as TranslationKey) : translateOrFallback(error, options)).

Improvements

1. Line 140 in an unspecified file: Added a condition to check if parsed.maxVerifiedTime exists before executing the code block.
2. Lines 142-146 in an unspecified file: Added new logic to calculate timeSinceCompletion based on currentBlockNumber and blockTimeMs.
3. File: captcha.ts
   • Line 140: The condition if (parsed.maxVerifiedTime) should be checked before accessing solution.completedAt to avoid potential errors.
   • Line 144: The calculation of timeSinceCompletion may result in unexpected behavior if currentBlockNumber or blockTimeMs is not available.
4. File: tasks.ts
   • Line 553: The return type of getBlockNumber is not specified. Ensure it returns a Promise<number> to avoid potential type errors.
5. One place in the code that could be refactored for better readability is in the prosopoRouter function in captcha.ts. Instead of calculating timeSinceCompletion inline, it can be extracted into a separate function for better organization and reusability. Here's a possible refactoring:

function calculateTimeSinceCompletion(currentBlockNumber: number, completedAt: number, blockTimeMs: number): number {
  return (currentBlockNumber - completedAt) * blockTimeMs;
}

export function prosopoRouter(env: ProviderEnvironment): Router {
  // ...
  if (parsed.maxVerifiedTime) {
    const currentBlockNumber = await tasks.getCurrentBlockNumber();
    const blockTimeMs = await tasks.getBlockTimeMs();
    const timeSinceCompletion = calculateTimeSinceCompletion(currentBlockNumber, solution.completedAt, blockTimeMs);

    if (timeSinceCompletion > parsed.maxVerifiedTime) {
      return res.json({ status: req.t('API.USER_NOT_VERIFIED'), solutionApproved: false });
    }
  }
  // ...
}

This refactoring separates the calculation of timeSinceCompletion into a dedicated function, making the code more modular and easier to understand.

Really tidies things up. A few small changes required.
