Unexpected token ? during run ionic 6 application on android virtual device

Question

I get this error:

JavaScript Error: {"type":"js.error","error":{"message":"Uncaught SyntaxError: Unexpected token?","url":"http://localhost/vendor.js","line":24288,"col":28,"errorObject":"{}"}} File: http://localhost/ - Line 582 - Msg: SyntaxError: Unexpected token? File: http://localhost/vendor.js - Line 24288 - Msg: Uncaught SyntaxError: Unexpected token?

when I run the application in the android emulator. And the app does not want to start, just crashes and shows this error in Logcat. I was open that file and this is what I find in that line:

this._baseHref = href?? this._platformLocation.getBaseHrefFromDOM()?? (0,_angular_core__WEBPACK_IMPORTED_MODULE_0__.inject)(DOCUMENT).location?.origin?? ''; which belongs to this: class PathLocationStrategy extends LocationStrategy

If helps I can share vendor.js file with you. But please help me or help me to address who is responsible for it.

Changed in tsconfig.json from:

into:

"target": "es2015",

and looks all works!
