tsconfig.json

I am getting error when I open tsconfig.json file:

JSON schema for the TypeScript compiler's configuration file

Cannot find type definition file for 'react-dom/next'.
The file is in the program because:
Entry point of type library 'react-dom/next' specified in compilerOptionsts
Cannot find type definition file for 'react-dom/next'.
The file is in the program because:
Entry point of type library 'react-dom/next' specified in compilerOptionsts

Why is this happening ?
But app works tho..

Start with tsconfig.json and inspect the compilerOptions types entry that names react-dom/next. Check how TypeScript resolves that type library and compare the diagnostic with the fact that the app still runs; done means explaining the cause and identifying a project-supported configuration or dependency state that removes the error.
