Symptoms
Issue at customer is as follows. We have the standard Sharepoint app for Sharepoint 2013 (version 1.0.0) installed and configured a set of SMOs for a document library. Using the standard generated SMOs we can upload small files, however as soon as the file size is larger than about 1.5 Mb ~ 2Mb then we get an error message:
404 Not found.
Diagnosis
We have run a Fiddler trace between K2 and SharePoint and you can see that it is actually a directory not found exception that is returned. We looked into the value of the @TargetLibrary in the REST response and we suspect that there is a missing "/" at the start of the value. One of our developers was able to confirm that when he posted as follows (as from the app) it gets an error:
POST https://portal.domain.com/sites/tutorials/howtok2/_api/web/GetFolderByServerRelativeUrl(@TargetLibrary)/Files/Add(url=@TargetFileName,overwrite=@Overwrite)?@TargetLibrary='sites/tutorials/HowToK2/Approved Documents'and@TargetFileName='DEV-B331.pptx'and@Overwrite='False' HTTP/1.1

However...
Solution:
When I add the '/' in front of 'sites' in @TargetLibrary, and execute a request again using fiddler composer, everything works:
POST https://portal.domain.com/sites/tutorials/howtok2/_api/web/GetFolderByServerRelativeUrl(@TargetLibrary)/Files/Add(url=@TargetFileName,overwrite=@Overwrite)?@TargetLibrary='/sites/tutorials/HowToK2/Approved Documents'and@TargetFileName='DEV-B331.pptx'and@Overwrite='False' HTTP/1.1
Response:
