Vocab.txt missing for distilbert squad on listed files

Hi there, I cannot auto-download models due to firewall, and would like to directly download the artifacts. It appears there is no vocab.txt available for distilbert-base-cased-distilled-squad or distilbert-base-uncased-distilled-squad

https://huggingface.co/distilbert-base-cased-distilled-squad#list-files

Any ideas how to move foward?

Managed to identify the relevant vocab.txt files for distilbert. Think having the vocab.txt related to a model, should also form part of the listed files.
