     * construct. If the current project is not a Node project, relative paths are
     * not reliable and absolute paths should be used.
     *
     * This file should be located underneath the `projectRoot` directory (by default,
     * the directory containing the package manager's lock file).
     *
     * If omitted, the entry file will be derived from the TypeScript/JavaScript file
     * that instantiates the `NodejsFunction` construct, and the construct identifier
     * of the `NodejsFunction` construct, in the following way:
     *
     * ```
     * <filename>.<construct-id>.(ts|js)

     * // Example, if stack.ts contains the following:
     * new NodejsFunction(this, 'my-handler', { ... });

     * // Then the implicit entry point(s) will be
     * stack.my-handler.ts
     * stack.my-handler.js
     * ```
     *
     * Again: if the current project is not a Node project this is not reliable,
     * and instead explicit, absolute paths should be used.
     *
     * @default - (Realible in Node projects only) derived from the defining file's name and construct ID as described in the documentation.
