Added a null check in `EnvelopeReceiverPage.razor` to log a warning when `_envelopeReceiver` is null. Updated `ReportViewer.razor` to wrap `EnvelopeReceiverService.GetAsync` in a `try-catch` block, logging `HttpRequestException` errors and allowing the UI to handle null values gracefully.
Enhanced `EnvelopeReceiverService.GetAsync` to throw detailed `HttpRequestException` on API failures, including status code and reason phrase. Added `using System.Net;` to support HTTP-related classes. Updated method documentation to reflect the new behavior.
These changes improve error diagnostics, logging, and maintainability across the codebase.
Refactored `DocumentService.GetDocumentAsync` to throw
`HttpRequestException` on failure instead of returning a tuple.
Updated all consumers to handle exceptions, improving error
handling consistency across the application.
Enhanced error messages for better user feedback and added
logging for improved traceability. Updated `EnvelopeReceiverPage`,
`EnvelopeReceiverPage_DxReportViewer`, and `ReportViewer` to
use the new exception-based API and handle errors gracefully.
This change simplifies the API, improves maintainability, and
makes the application more robust and user-friendly.
