Catching error “QueryKey value not found in link output” when fetching taxonomy from NCBI

Dear reader!

I intend to retrieve the taxonomy for some accession numbers in NCBI using the following command:

Using the following example:
www.ncbi.nlm.nih.gov/protein/XP_018619665.1

I run this command:

esearch -db protein -query "XP_018619665.1" | elink -target taxonomy | efetch -format native -mode xml | grep ScientificName | awk -F ">|<" 'BEGIN{ORS=", ";}{print $3;}'

The above example returns:

"QueryKey value not found in fetch input"

I believe the reason is that the sequence has been updated.

I am now wondering how I can handle this kind of error within the terminal or within R?
This command is used within R in part of my code.
