DOCXKIT_PREVIEW_INPUT_INVALID: Invalid preview input

The preview input is absent or not one of the supported input types.

What to do

1. Pass a DOCX Blob, ArrayBuffer, Uint8Array, or URL.
2. Wait for generation to finish before starting preview.

Problem example

// Invalid external input:
const input = null

Corrected example

import { createDocx, createDocxPreview } from 'docx-kit'

const container = document.createElement('div')
document.body.append(container)

const preview = createDocxPreview(container)
try {
  await preview.render(await createDocx().p('Hello').toBlob())
} finally { preview.destroy() }

Common causes

• Null input or an unsupported object/string type.
