[Solved] How to get a sharing link for a file using its UUID

Hi, I put a new object into my workspace via the svc.PutObject(input) command and use the returned UUID to try and get a sharing link with Pydio Cells. This is the response from my PUT request:
CreateNode {"node": "Uuid:\"a4d703c4-acc2-4ad1-9d69-11d1c56c1f4a\" Path:\"admin/test.txt\" Type:LEAF Size:5 MTime:1543502791 Mode:511 Etag:\"5d41402abc4b2a76b9719d911017c592\" "}

But when I use that UUID to get a sharing link like so:
shareLink, err :=api.ShareService.GetShareLink(&share_service.GetShareLinkParams{UUID:"a4d703c4-acc2-4ad1-9d69-11d1c56c1f4a", Context:ctx, HTTPClient:http.DefaultClient})
I get this error:
Rest Error 404 {"error": "{\"id\":\"share\",\"code\":404,\"detail\":\"Cannot find workspace with Uuid a4d703c4-acc2-4ad1-9d69-11d1c56c1f4a\",\"status\":\"Not Found\"}"}

Do I have to put the share link first? Using the following code:
var shareLinkRest = &models2.RestShareLink{UUID:"a4d703c4-acc2-4ad1-9d69-11d1c56c1f4a"}
var shareBody = &models2.RestPutShareLinkRequest{ShareLink:shareLinkRest}
shareLink, err :=api.ShareService.PutShareLink(&share_service.PutShareLinkParams{Body:shareBody,Context:ctx, HTTPClient:http.DefaultClient})

I get the same error from my pydio cells server

When I set the root nodes (as it appears the browser frontend does) like so:
nodes:= []*models2.TreeNode{{UUID: "a4d703c4-acc2-4ad1-9d69-11d1c56c1f4a" }}
var shareLinkReq = &models2.RestShareLink{ RootNodes: nodes,}

I get this error:

What am I missing?
thanks,
Ian

I had to set all of the parameters in the RestShareLink like this:
var shareLinkReq = &models2.RestShareLink{ RootNodes: nodes, Permissions:accesTypes,Label:"test.txt", PoliciesContextEditable:true, ViewTemplateName:"pydio_unique_strip", Description:"This is a veryyyyy interesting text file we have here"}

So you solved this one?

Yes, sorry, is there a way to mark it as solved? I would love your input on this: Can't add a custom filename to a presigned put request
