In tsconfig.json, why does it say "Build: No inputs were found in the configuration file"?

edit

This error message means that the TypeScript compiler cannot find any source files to compile based on the configuration settings specified in the tsconfig.json file. Typically, this occurs when the "files" or "include" properties in the tsconfig.json file are empty or are pointing to non-existent files or directories. To resolve this, ensure that the "files" or "include" properties are correctly defined and that the source files are located in the specified directories.
