Argument 'id' is required.

Error message

Argument 'id' is required.

What it means

This AMD-style module loader shim's `define` function requires a module id as its first argument. Anonymous modules are not supported by this Pentaho loader implementation, and ArgumentRequiredError cannot be used here because Base.js itself depends on this module (cycle prevention). It throws a plain Error whenever the id argument is missing or not a string.

Solutions

1. Add a string module id as the first argument to define()
2. If the module comes from a bundle, re-run the optimizer (r.js) so each define gets an explicit id
3. Wrap anonymous define calls with a named define shim assigning a module path

Example fix

// before
define(['pentaho/util/Base'], function(Base) { ... });
// after
define('my/plugin/MyModule', ['pentaho/util/Base'], function(Base) { ... });

if (typeof id !== "string" || id.length === 0) throw new Error("define() requires a non-empty string module id");

function hasModuleId(args) { return args.length > 0 && typeof args[0] === "string" && args[0].length > 0; }

When it happens

Trigger: Calling `define()` with no arguments, `define(null)`, `define(function(){...})` (anonymous module), or `define(123, ...)` with a non-string id.

Common situations: Porting third-party AMD modules that rely on anonymous defines (bundlers like r.js usually generate ids); hand-written modules omitting the id; refactoring that dropped a string literal id.
