@Admin Limna Thank you for reaching out to Microsoft Q&A. This question is similar to other thread, and I just posted an answer to the thread. To summarize, Document
type is no longer available if you use Microsoft.Azure.WebJobs.Extensions.CosmosDB
with version 4.0.0. Also, there is no such type as Item
and the recommendation is to use C# type instead of generic types. Please refer examples posted in SDK repo about Usage such as delete an item or read item etc.
