What is node_source_map_error? It says that the source map was missing or invalid. Or, to be more accurate, it says that a source map for this file was not found or was invalid.
JavaScript files are "compiled" from typescript. That process must have been successful.
Latest node version：node v14.15.3
OS：Windows 10
IDE：Visual Studio Code with Insiders Build
Example File：Index.ts
After receiving a node_source_map_error, you probably checked node version and reinstall node. And you did that already but still seeing source map error?
Is your node source map error happening when you try to compile a .ts file? Or while running a node.js script?
Let’s start fixing the node source map error by checking node installation folders.
What Are Source Maps？
Source Maps are text files generated alongside JavaScript code when a program is compiled. They are very helpful for debugging because when an error happens at runtime, you get the line number corresponding to the source file.
node_source_map_error might occur if you are running a typescript file. TypeScript is a language that compiles to javascript. Without this source map, an uncaught error in javascript is hard to trace back to the typescript source.
You might also see similar errors when using browser dev tools with compiled code. In many cases, source maps make your debugging sessions much easier.
To fix node_source_map_error you must locate the .map file or delete the conflicting one.
Are you using WinJS？ WinJS still requires source maps for debugging on Windows Store Apps. But again, if you are not debugging, you don\'t need source maps.
The solution starts with the following questions：
Is node_source_map_error appearing in your terminal?
Is it appearing in the browser developer tools？
Or is the error message being displayed in your IDE like VS Code？
