Resolution/Workaround:

  1. Unzip the original package (rename to .zip)
  2. Open each xml file in notepad
  3. For any that start with cartridge_basiclti_link and don't already include <blti:vendor>, add the following:
<blti:vendor>
    <lticp:code>a</lticp:code>
    <lticp:name>a</lticp:name>
    <lticp:description>a</lticp:description>
</blti:vendor>
  1. Save changes, re-zip everything and rename back to .XXXX (original name of file) and it should import without error
