265-268: Verify the impact on error handling flowThe error thrown here is caught in multiple places. Ensure consistent error handling across all code paths.
Let's verify the error handling paths:
✅ Verification successful
Error handling for invalid access key is properly implemented
The error handling for invalid access keys is consistent across the codebase:
- The validation occurs in the access key parsing logic, throwing an "Invalid access key" error
- This error is caught within the higher-level
handleErrorwrapper function (as seen in the try-catch blocks)- Different error scenarios are handled appropriately:
- Invalid access key format triggers the validation error
- Forbidden (403) responses are handled separately
- JSON parsing errors are caught and processed
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Check error handling for invalid access keys # Look for catch blocks handling parseAccessKey errors rg -A 5 "catch.*{" src/app-simplefin/Length of output: 119
Script:
#!/bin/bash # Let's fix the regex and search for catch blocks rg -A 5 "catch\s*\{" src/app-simplefin/ # Also search for any error handling related to access key validation rg -B 3 -A 3 "Invalid.*access key" src/app-simplefin/ # Look for try blocks that might be related to access key handling rg -B 3 -A 3 "try\s*\{" src/app-simplefin/Length of output: 2897

🛠️ Refactor suggestion
Enhance error messages for better debugging
The current error message "Invalid access key" doesn't provide enough context about what specifically is wrong with the format.
Consider providing more specific error messages:
- throw new Error(`Invalid access key`);
+ throw new Error('Invalid access key format. Expected format: https://username:[email protected]');📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
| if (!accessKey || !accessKey.match(/^.*\/\/.*:.*@.*$/)) { | |
| console.log(`Invalid SimpleFIN access key: ${accessKey}`); | |
| throw new Error(`Invalid access key`); | |
| } | |
| if (!accessKey || !accessKey.match(/^.*\/\/.*:.*@.*$/)) { | |
| console.log(`Invalid SimpleFIN access key: ${accessKey}`); | |
| throw new Error('Invalid access key format. Expected format: https://username:[email protected]'); | |
| } |
Security: Remove sensitive data from error logs
The current implementation logs the full access key which contains credentials. This poses a security risk as credentials could be exposed in log files.
Apply this change to remove sensitive data from logs:
- console.log(`Invalid SimpleFIN access key: ${accessKey}`);
+ console.log('Invalid SimpleFIN access key format');📝 Committable suggestion

🛠️ Refactor suggestion
Strengthen the access key validation
The current regex pattern (^.*\/\/.*:.*@.*$) is too permissive and could allow malformed URLs. Consider these improvements:
- Validate scheme is 'http://' or 'https://'
- Ensure username and password are not empty
- Validate the base URL format
Consider applying this improved validation:
- if (!accessKey || !accessKey.match(/^.*\/\/.*:.*@.*$/)) {
+ if (!accessKey || !accessKey.match(/^https?:\/\/[^:]+:[^@]+@[^/]+$/)) {
console.log('Invalid SimpleFIN access key format');
throw new Error(`Invalid access key`);
}
+ // Additional validation after splitting
+ [scheme, rest] = accessKey.split('//');
+ if (!['http:', 'https:'].includes(scheme)) {
+ throw new Error('Invalid scheme: must be http or https');
+ }
+ [auth, rest] = rest.split('@');
+ [username, password] = auth.split(':');
+ if (!username || !password) {
+ throw new Error('Missing credentials');
+ }
+ if (!rest || !rest.includes('.')) {
+ throw new Error('Invalid base URL');

Adds a check to ensure the SimpleFIN accessKey is in the expected format. Helps avoid silent errors if the key was invalid (e.g., if CloudFlare blocked the call).
