TypeErrorTypeError
A value is not of the expected type. This is the most common JavaScript error, occurring when an operation encounters a value of the wrong type.
ERR_MODULE_NOT_FOUNDAn ES module import could not be resolved because the specified file does not exist.
The import path does not resolve to an existing file. ES modules require full file extensions (.js, .mjs) unlike CommonJS require(). The file may not exist, the path may be wrong, or the extension may be missing.
Add the full file extension to your import path: import x from './file.js'. Verify the file exists at the specified path. Check that relative paths are correct from the importing file's location.
