Error message

EmbedIframeService or LinkPreviewService not found

What it means

parseIdentifier accepts only two shapes: an Identifier created by createIdentifier (a callable carrying identifierName/variant), or a named class/constructor from which a stable name+hash identifier is derived. Anything else — strings, undefined, numbers, plain objects, anonymous functions — cannot be mapped to a service key, so it throws 'Input is not a service identifier.' before any registry lookup happens. Unlike string-token DI libraries (inversify/tsyringe), raw strings are not valid tokens here.

Solutions

1. Create identifiers with createIdentifier<T>('Name') and pass that callable to impl/get/getAll
2. Fix the circular import so the identifier is defined when get()/impl() runs — move identifiers to a leaf module or reorder imports
3. Never pass strings or plain objects as identifiers; if you meant class-as-identifier, pass the class itself (it must have a .name)

Example fix

// before
provider.get('Storage'); // strings are not identifiers

// after
const Storage = createIdentifier<Storage>('Storage');
fw.impl(Storage, LocalStorage);
provider.get(Storage);

null

function isIdentifier<T>(x: unknown): x is Identifier<T> {
  return typeof x === 'function' && typeof (x as any).identifierName === 'string';
}

// guard before resolving
if (!isIdentifier(Storage)) throw new Error('Storage identifier not initialized (circular import?)');
provider.get(Storage);

When it happens

Trigger: provider.get('Storage') expecting a string token; passing undefined because a circular ESM import left the identifier module half-evaluated; passing a plain object or a value obtained by destructuring/wrapping the Identifier; passing an anonymous function expression (empty .name).

Common situations: Migrating code from a string-token DI container; circular imports where `export const Storage = createIdentifier(...)` is consumed before evaluation; identifiers re-exported through barrel files involved in a cycle.
