sharepoint file uploded from code not appearing with CRM record ?

i m uploading file to sharepoint from code and then creating SharePointDocumentLocation
record to attach document with Crm record.

I can see file uploaded to shrepoint under this folder (example):

https://mysharepoint.com/sites/canas/canas/Test%20name%203%20-%20Monthly%20Order%20-%202017_07e2fb8d-3237-e811-8181-e0071b66a1e1 

So I see file if I navigate to:

https://mysharepoint.com/sites/canas/canas/Test%20name%203%20-%20Monthly%20Order%20-%202017_07e2fb8d-3237-e811-8181-e0071b66a1e1/file.txt 

For this part first I m saving entity record, then upload document to sharepoint and in last creating SharePointDocumentLocation.

Problem is when I go to CRM record > documents I dont see document there :(

I even have tried to upload a document manually form crm but getting error:

clicking technical details it do not shows any other details but just this message.

please help
