Javascript always failing

Question

I am busy writing some javascript to take a list of selected documents and do some processing on a list with each document in Office365. I am getting a strange error when the code tries to load the document from the absolute URL. The document is guaranteed to be in the same SP.Web that the JS is in.

The error is

Value does not fall within the expected range.

Below is the JS I have:

function GetFile(attachment, item) {
   var fileContext = SP.ClientContext.get_current();

   var site = fileContext.get_site();
   fileContext.load(site);

   fileContext.executeQueryAsync(function() {
       var relUrl = attachment.Url.replace(_spPageContextInfo.siteAbsoluteUrl, '');

       var file = fileContext.get_web().getFileByServerRelativeUrl(relUrl);

       fileContext.load(file, 'ListItemAllFields');

       fileContext.executeQueryAsync(
           function () {
               var listItem = file.get_listItemAllFields(); 
           },
           function (sender, args) {
               console.log(args.get_message()); //errorhandling
           }
       );
   }, function(sender, args) {
       console.log(args.get_message());
   });  
}

This is not a permissions thing as I can take the url of the documents being selected and open them fine from the browser.

I have noticed, that I can't seem to hit the client.svc service on the site in question when taking the url for the request from the request object.

Answer 1

The error Value does not fall within the expected range usually occurs when the file specified via serverRelativeUrl parameter in SP.Web.getFileByServerRelativeUrl Method does not exists, so make sure the url has the following format:

/<site>/<list url>/Attachments/<item id>/<attachment name>

I guess (since it is not clear from question) attachment.Url stores the location of AttachmentFile. In that case SP.File.listItemAllFields property will be empty since attachment file is not associated with list item.

Answer 2

You suggestion of the "file doesn't exist" led me down the right road. The url I was using to grab the file was kissings /sites/ which was getting removed by the following:

var relUrl = attachment.Url.replace(_spPageContextInfo.siteAbsoluteUrl, '');

I have made some changes to it and it now loads the file as expected.
