Start with the reported Oryx build command and trace the stack from BuildScriptGenerator.DefaultPlatformsInformationProvider through HugoDetector.cs and ParserHelper.cs, especially ParserHelper.cs line 86. Compare the detector's JSON input with the reported StartArray error; done means the Node.js build can complete without this detection failure, with a regression test if an existing detector test location is found.
