I got this exception while trying to convert a docx file to pdf using docx4j-export-fo 11.4.11:
org.apache.fop.fo.ValidationException: Missing attribute on fo:basic-link: Either external-destination or internal-destination must be specified. (See position 1:3993)
Upon closer inspection of the source docx file I found a element without r:id attribute. It appears that this element maps to the 'link without destination' in the error message. Manually removing this element seems to solve the issue.
I am not sure when or how this 'link without destination' ended up in the docx source file...
However Word doesn't consider it an issue that this element exists in the document. Word doesn't give a warning of a corrupted file / document and does not automatically replace the 'link' with plain text upon edit or save. Instead Word just leaves the element as-is and renders it as plain text.
Ideally docx4j-export-fo would handle this the same way Word does: render the element as plain text in case the 'link' has no destination.
