Thanks for the response. Is there a workaround or a part of the document we can remove to prevent this error?

Thanks,

For future readers, this is the workaround that we settled on. No guarantees that this will work for all cases, but it seems to work for our tests:

Try({
  // Only apply this to structured document tag nodes in the document that contain paragraphs
  // that contain shapes.
  val structuredBlocks = asposeDoc
    .getChildNodes(NodeType.STRUCTURED_DOCUMENT_TAG, true).asScala
    .map(*.asInstanceOf[StructuredDocumentTag])
    // Filter based on a paragraph containing a shape.
    .filter(*.getChildNodes.asScala
      .filter(*.isInstanceOf[Paragraph])
      .map(*.asInstanceOf[Paragraph])
      // Check if the paragraphs children are shapes.
      .exists(*.getChildNodes.asScala.exists(*.isInstanceOf[Shape]))
    )
  structuredBlocks.foreach(structuredBlock => {
    val parentNode = structuredBlock.getParentNode

    // Remove the structured block from the document, moving it’s children into the parent.
    // Using foldLeft to ensure that the children are inserted in order in the correct place
    // in the parent.
    structuredBlock.getChildNodes.asScala.foldLeft(structuredBlock.asInstanceOf[Node])({
      case (previous, node) => {
        node.remove()
        parentNode.insertAfter(node, previous)

        node
      }
    })
    structuredBlock.remove()
  })

  // This refreshes internal state so the changes made above are applied.
  asposeDoc.updatePageLayout()
})
