The "csrContent" in the certificate downloaded is null. I would not be surprised if this was the culprit... but I am at a loss as to how to download the certificate as is, inject the CSR and then use it all in code. (Im writing c# server code by the way in case it matters).
Of course - that's assuming this csrContent is the culprit.
