Root Cause Analysis

Problem

• req.baseUrl is here always an empty string https://github.com/SAP/open-ux-tools/blob/c0f92980c658ad2fc9f28de75b3e778d5fa36559/packages/ui5-proxy-middleware/src/base/utils.ts#L275-L280
• htmlFilePath will be just the webapp folder instead of the path to the requested HTML file
• that's why the further logic doesn't work and instead of replacing the URL in injectUI5Url it tries to read the webapp directory

Fix

• just use reg.url or reg.originalUrl
