Opc.Ua.CertificateGenerator not working on CSR|OPC UA Standard|Forum|OPC Foundation

Hello,

I am trying to implement certificate management with a GDS. 
I have a client that is attempting to call CreateRequest to generate a CSR.

The issue I am running into is that the call throws an exception: "input file was not processed properly"

When checking the tmp file that gets generated by the command and called by opc.ua.certificategenerator, I notice that it does not change to contain "-requestFilePath"
It still has the original content starting with "-cmd request", hence the error.

I tried running the command opc.ua.certificategenerator.exe -f <path/to/tempfile> and it still did not work.
I am also not getting any errors or logs.

Are there any ideas as to why the certificategenerator is not working?
Information below:

CertificateGenerator version is

1.1.336.4

temp file written for generator:

-cmd request-publicKeyFilePath 3082046930820351A003020102021008DC90DFC3A3D64D8709CB0FAA811B38300D06092A864886F70D01010B05003050311C301A060A0992268993F22C640119160C47434E443732373036315445311A3018060355040A0C11556E69666965644175746...-privateKeyFilePath 3082054E0201033082050A06092A864886F70D010701A08204FB048204F7308204F3308204EF06092A864886F70D010706A08204E0308204DC020100308204D506092A864886F70D010701301C060A2A864886F70D0...-hashSize 256
