Custom WOPI Implementation

Question

I am trying to implement previews(WOPI) for my files stored in local file system. I am trying to implement it using the Office Online Server Farm we have. I used the below code but its calling the "Get" endpoint but after that its not calling the "contents" end point.

Answer 1

Finally I identified the issue. The Version field should be string like "1.0.0.0" instead of int.
