SharePoint Client Object Model “Field does not exist” error

Mike BerrymanI was working with the SharePoint Client Object Model in Javascript a couple days ago and ran into the ever-so-common not-helpful error message of “Field does not exist” whenever any user other than myself would try and create a list item.  The weird part was, despite this error message, the list item was being created perfectly with no issues, with the field in question filled in exactly as entered on the form.  The only reason I knew there was an error was the fail callback function was being triggered, and consequently an alert box popping up with the “Field does not exist” error.

“The root of the certificate chain is not a trusted root authority”

Scott ZischerkI recently ran into an issue where a web service that I had set up through SharePoint was throwing the error: “The root of the certificate chain is not a trusted root authority”  The web service ultimately sent out an email with an attachment that is retrieved from a SharePoint document library.  The error was occurring when I created a HttpWebRequest and called the GetResponse method.  Initially, I tried to reassign the ServicePointManager.ServerCertificateValidationCallback property to a method that just returns true, but that didn’t seem to work.

Eventually, I found this blog post: that had me download all the certificates in the SSL certificate chain and add them into SharePoint.  After adding the root, intermediate and SSL certificate the web service started working properly.
