VS Code ignoring break points when debugging typescript program -


i have hello world program on typescript:

function say(msg: string) {     alert(msg);     (let i:number=0;i<10;i++)         document.write(i+"<br/>"); } var msg:string="hello typescript world!"; say(msg);

this code inside src folder. when run compiler (tsc) generates *.js , *.map files , put them inside src folder.also there index.html in root of project

<html> <body> <script type="text/javascript" src="src/hello.js"></script> </body> </html>

but when run debug session in chrome breakpoints ignored message

breakpoint ignored because generated code not found (source map problem?)

in web server logs can see following line:

"get /src/hello.js.map" "undefined"

tsconfig.json:

{   "compileroptions": {     "sourcemap":true,     "target": "es5",     "module": "commonjs",     "noimplicitany": false   } }

launch.json:

{     "version": "0.2.0",     "configurations": [         {             "type": "chrome",             "request": "launch",             "name": "debug in chrome",             "url": "http://localhost:8080",             "webroot": "${workspaceroot}"         }     ] }

update: when trying set breakpoint chrome debugging tool stop on breakpoint doesn't show js/ts code:
breakpoint added breakpoint added

breakpoint reached breakpoint reached

it looks there issue vs code.i started new project same launch.json,tsconfig.json , source code , debugging ok in chrome!then copied initial project , debugging ok too.
