not-initialized

All codes

  • Type: error
  • Kind: state (the call isn’t valid in the object’s current state)

What happened

A function or class of @lamina/pdf (Document.open, new Builder, …) was called before init() had finished loading and instantiating the WebAssembly module.

Why

@lamina/pdf is synchronous after init() (ADR 0016 §3), but fetching and compiling the .wasm file is asynchronous, so it happens once, up front, in init(). Until that promise resolves there is no module to call.

How to fix

Await init() once, before the first call; calling it again is cheap (it is idempotent). In a Cloudflare Worker, pass the imported module: await init({ module: wasm }).

Example

import { Document, init } from "@lamina/pdf";
Document.open(bytes); // throws { code: "not-initialized", … }
await init();
Document.open(bytes); // works

Data fields

None.
