- This is a crash
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')

Added some debug output in this js file:

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.
