Just Change the Lib on tsconfig.json Before : { "files": [ "src/*.ts", "src/model/*.ts" ], "compilerOptions": { "noImplicitAny": true, "target": "es5" } }

After : { "files": [ "src/*.ts", "src/model/*.ts" ], "compilerOptions": { "noImplicitAny": true, "target": "es5", "lib": ["es5", "es2015.symbol", "es2015.symbol.wellknown"] } }

i think this fixed the issue.

For a temp fix I have edited from Library | Symbol thing which I don’t remember now. But I just removed it and it got compiled and working fine. issue is its not in ES6 format and outdated right now.
