  • Initial plan created and problem analyzed
  • Located the specific tuple error in ExpressionBuilderContext.TypeFor.cs line 228
  • Found problematic libraries (CMS2FHIRPCSDepressionScreenAndFollowUp, CMS145FHIRCADBetaBlockerTherapyPriorMIorLVSD, CMS832HHAKIFHIR)
  • Identified root cause: tuple elements with AliasRef values that have neither resultTypeSpecifier nor resultTypeName
  • Implemented enhanced TupleTypeFor method with GetTupleElementTypeSpecifier helper
  • Added CreateTypeSpecifierFromType method to convert .NET types back to TypeSpecifiers
  • Updated MissingResultTypeSpecifierCorrector to handle basic cases (resultTypeName → NamedTypeSpecifier)
  • Removed problematic files from SkipFiles list in ecqm-content-qicore-2025.appsettings.json
  • Built and tested the solution successfully
  • Verified tuple error no longer occurs when processing ELM libraries
  • Added regression test to prevent future issues
  • All tests pass

Summary

Fixed issue #1012: "Tuple element value does not have a resultTypeSpecifier" by implementing a robust type inference mechanism for tuple elements that don't have explicit type information. The solution follows the Java algorithm approach mentioned in the issue description and gracefully handles missing type specifiers by attempting to infer types from element values.

The fix enables processing of previously problematic ELM libraries while maintaining backward compatibility and providing clear error messages when type inference fails.

@copilot , continue resolving this issue after I merged from develop

Enhanced ExpressionBuilderContext.TypeFor to handle tuple elements that don't have explicit resultTypeSpecifier or resultTypeName by attempting to infer the type from the element value. This resolves the "Tuple element value does not have a resultTypeSpecifier" error that was preventing processing of libraries like CMS832HHAKIFHIR.

The fix follows the Java algorithm approach by:
1. Checking if resultTypeSpecifier is available (use directly)
2. Checking if resultTypeName is available (create NamedTypeSpecifier)
3. Attempting to infer type from element value using existing TypeFor logic
4. Converting inferred .NET type back to TypeSpecifier format
5. Providing meaningful error message if type cannot be determined

Added test case and removed the problematic files from SkipFiles list in the ecqm-content-qicore-2025 configuration.
