How do you update DOCV metadata via Fusion?

[stuartcairns]

I am trying to update DOCV metadata via Fusion, following the code here https://developer.workfront.com/otherD.html#get-/docv/metadata but I'm getting an error saying "[422] APIModel V13.0 does not support field data (DocumentVersion)".  I've tried with the various API version options with the same result.  I'm trying to update the externalStorageID using this JSON code(following the guide above)  {"data":{"externalStorageID":{"url":"{{36.value}}"}}}  where 36.Value is input from an upstream module that contains URL to go into the externalStorageID.

Any clues, anyone.

Best regards

Stuart
