I applied your patch and it resolved the error but what I noticed is that
if a metadata field has no value selected, the metadata is still applied to
document, albeit with no value. I believe it should not be applied to the
document at all. So I think there needs to be a second part to this patch
that checks if a value has been defined before applying the metadata to the
document. I had a look at the code but it is way beyond my coding abilities
:(
Thank you for this patch which helped me move forward in my testing.
