Internal Error Types

Back to Error Reference

Overview

The compiler uses several internal error categories that appear in JSON diagnostic output:

Type	Source	Description
CompilerError	Validation and semantic analysis	Standard compilation errors with E-codes
IrGeneration	IR lowering (Stage 5)	Errors during IR generation with context
ManifestGeneration	Artifact builder (Stage 8)	Manifest permission policy violations
Generic	Various stages	Catch-all for unclassified errors

IR generation errors include additional context fields in JSON output:

{
  "component": "neo-devpack-solidity",
  "severity": "error",
  "type": "IrGeneration",
  "message": "unsupported feature: inline assembly",
  "functionName": "computeHash",
  "errorCode": "E3001",
  "suggestion": "Use CryptoLib.sha256() from the devpack instead"
}
