Problem statement

Trying to connect RavenDB Cloud service using AWS Lambda function, for one of my POC, but failed to connect.

Background

I am using the client certificate (.pfx) file for this. It throws error exactly during certificate assign with X509Certificate2. I have converted the certificate to byte[] and passed. The certificate I am using has full access to the database. I am included the error below

Code

            if (_bClientCertificate != null)
            {
                if (_bClientCertificate.Length > 0)
                {
                    xclientCertificate = new X509Certificate2(_bClientCertificate);
                }
            }

             IDocumentStore store = new DocumentStore()
            {
                Certificate = xclientCertificate, //Error occured here

                Urls = _Urls,
                Database = _DBName
            }.Initialize();

I've had this issue before, apparently some visual C++ libraries could be missing. Try installing Visual C++ Redistributable for Visual Studio 2015.
