From 650d6ca730df99522ef0065f03ea7bca6b37da2b Mon Sep 17 00:00:00 2001 From: hongwei Date: Wed, 4 Feb 2026 11:01:13 +0100 Subject: [PATCH] refactor/(http4s): enhance error handling and request conversion for bridge parity - Replace NotFoundResponse with JSON error responses in Http4sLiftWebBridge for consistent error formatting - Improve Content-Type header extraction with fallback to header parameters when contentType is unavailable - Fix query parameter extraction to use parsed queryParams instead of raw URI query parsing - Add wrappedRoutesV500ServicesWithJsonNotFound for standalone JSON 404 responses - Add wrappedRoutesV500ServicesWithBridge for production-like fallback behavior to Lift bridge - Fix multi-value query parameter handling in Http4sRequestConversionPropertyTest by adding all values at once - Update authenticatedEndpoints to use path segments instead of string literals to avoid URL encoding issues - Enhance logging messages to indicate JSON 404 responses are being returned - These changes improve parity between Http4s and Lift implementations and provide better error diagnostics --- .../api/util/http4s/Http4sLiftWebBridge.scala | 22 ++++-- .../scala/code/api/v5_0_0/Http4s500.scala | 27 +++++++ .../Http4sRequestConversionPropertyTest.scala | 12 +-- .../Http4sLiftRoundTripPropertyTest.scala | 74 +++++++++---------- .../api/v5_0_0/V500ContractParityTest.scala | 4 +- 5 files changed, 87 insertions(+), 52 deletions(-) diff --git a/obp-api/src/main/scala/code/api/util/http4s/Http4sLiftWebBridge.scala b/obp-api/src/main/scala/code/api/util/http4s/Http4sLiftWebBridge.scala index 52e0d895b..5076bbe11 100644 --- a/obp-api/src/main/scala/code/api/util/http4s/Http4sLiftWebBridge.scala +++ b/obp-api/src/main/scala/code/api/util/http4s/Http4sLiftWebBridge.scala @@ -92,8 +92,9 @@ object Http4sLiftWebBridge extends MdcLoggable { logger.debug(s"Http4sLiftBridge handler returned Failure: $msg") APIUtil.errorJsonResponse(msg) case Empty => -
