instance-reset

All codes

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

What happened

A document, page, builder or save job was used after its WebAssembly instance was replaced. reset() replaces every loaded module’s instance, and a trap (wasm-trap or out-of-memory) replaces the instance that trapped. The handle belonged to the old instance, so it has nothing left to work on.

Why

Each handle lives in one instance’s memory, and a fresh instance starts empty. Lamina PDF can’t move a document across, so every handle from the old instance stops working at once.

How to fix

Open the document again from its bytes, or create a new builder. Unsaved edits are lost with the old instance, so save often in an app that calls reset() or may run out of memory.

Example

const doc = Document.open(bytes);
reset();
doc.pageCount; // throws LaminaPdfError { code: "instance-reset", … }

Data fields

None.
