invalid-argument

All codes

• Type: error
• Kind: usage (the caller misused the API)

What happened

A value passed from JavaScript to @laminapdf/wasm is not of the type its declaration describes. It might be a record with a field of the wrong type, or a string that names no known value (a blend mode, a fill rule, a standard 14 font, an op). It might also be a flat-encoded path cut short, a colour with the wrong number of components, or an ID that isn’t 32 hex digits.

Why

The .d.ts types describe each argument, but JavaScript (and code written without the types) can pass anything. The binding checks each value as it converts it.

How to fix

Pass what the declaration says. When the value names an unknown string, didYouMean lists the closest allowed ones; data.detail says what the conversion found.

Example

page.blendMode("multiplly"); // throws { code: "invalid-argument", didYouMean: ["multiply"], … }

Data fields

• argument: the parameter that was wrong (options, path, mode, …).
• detail: what the conversion said (untrusted: it may quote the value passed).
