I am converting some old code from module=none to module=es2015.
After changing the code and tsconfig I get
in folder: C:\tfs\TwinCAT-HMI\TcHmiFramework ...C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:16219 return option.strictFlag ? getStrictOptionValue(options, option.name) : options[option.name]; ^ TypeError: Cannot read properties of undefined (reading 'outFile') at getCompilerOptionValue (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:16219:88) at C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:10977:33 at Array.some (<anonymous>) at optionsHaveChanges (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:10976:64) at Object.compilerOptionsAffectDeclarationPath (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:16214:16) at createBuilderProgramState (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:100565:17) at Object.createBuilderProgram (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:101181:21) at createEmitAndSemanticDiagnosticsBuilderProgram (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:101554:19) at Object.host.createProgram (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:106634:20) at createProgram (C:\tfs\TwinCAT-HMI\TcHmiFramework\node_modules\typescript\lib\tsc.js:104850:28) TypeScript/src/compiler/utilities.ts

Added some debug output in this js file:
option: { name: 'outFile', type: 'string', affectsEmit: true, affectsMultiFileEmitBuildInfo: true, affectsDeclarationPath: true, affectsBundleEmitBuildInfo: true, isFilePath: true, paramType: { code: 6035, category: 3, key: 'FILE_6035', message: 'FILE', reportsUnnecessary: undefined, elidedInCompatabilityPyramid: undefined, reportsDeprecated: undefined }, showInSimplifiedHelpView: true, category: { code: 6246, category: 3, key: 'Emit_6246', message: 'Emit', reportsUnnecessary: undefined, elidedInCompatabilityPyramid: undefined, reportsDeprecated: undefined }, description: { code: 6679, category: 3, key: 'Specify_a_file_that_bundles_all_outputs_into_one_JavaScript_file_If_declaration_is_true_also_designa_6679', message: "Specify a file that bundles all outputs into one JavaScript file. If 'declaration' is true, also designates a file that bundles all .d.ts output.", reportsUnnecessary: undefined, elidedInCompatabilityPyramid: undefined, reportsDeprecated: undefined }, transpileOptionValue: undefined } options: undefined Changed the line to
return option.strictFlag ? getStrictOptionValue(options, option.name) : options?.[option.name];
and got a working compile.
After that the unchanged typescript compiler works again. So I suspect a problem with an old tsconfig.tsbuildinfo.
