Hi @david-gibbs-ig ,
Errors refer to the @vonage/server-sdk which has had a version update.
Based on the Vonage provider’s doc (which covers the migration guideline):
The Node SDK v3.x uses Promises instead of callbacks. Customers need to convert their callbacks to work with the responses returned from the calls.
Hope this helps, please let us know how it goes / if we can assist you further. Thanks!
