When I change "module" in tsconfig.json to 'ESNext' and "type" in package.json to 'module', I get an error

Question

When I compile my TS code to JS, I want the JS to use ESNext import/export and not CommonJS import/export. When I change "module" in tsconfig.json to 'ESNext' and "type" in package.json to 'module' for this purpose, I get an error:

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for G:\TechPro424\Other\Documents\GitHub\MultiBot\src\index.ts

}

index.ts is the file that I start to run the program.

My tsconfig.json:

Maybe you should remove "type": "module", Well it worked for me.
