Handling errors

This package provides structured ways to map and handle different types of errors. Below are common error keys you might encounter:

• the-certificate-password-is-incorrect: The certificate password provided is incorrect.
• invalid-certificate-file: The provided certificate file is invalid.
• invalid-certificate-base64string: The certificate Base64 string is malformed or invalid.
• empty-certificate-password: The certificate password cannot be empty.
• empty-certificate-base64string: The certificate Base64 string cannot be empty.
• could-not-find-the-certificate-path: The system could not locate the certificate file at the specified path.
• client-id-cannot-be-empty: The Client ID must be provided.
• date-range-must-be-in-the-same-month: Filtering is restricted to within the same calendar month.

Troubleshooting

Common Issues

1. Certificate Parsing Errors:
   • Ensure your .pfx or .p12 certificate is valid and not expired.
   • Double-check the password; it must match the one set when the certificate was exported.
2. Connectivity Issues:
   • Ensure your application has internet access and can reach api.sicoob.com.br.
   • Verify that your Client ID is correctly registered on the Sicoob Developers Portal.
3. Authentication Failures:
   • Confirm that the certificate corresponds to the Client ID used.
   • Ensure you are using the correct production or sandbox URLs (currently defaults to production).
