I am trying to follow the pnp partner pack setup process. After closely following instructions and three attempts, I get the oops exception value: null parameter:certificate when loading the pnp site. All of the bits were downloaded from git hub last week. I think this is a common issue but I can't find any related posts here. Any ideas what to check? Should I wait for the upcoming 2.0 launch?Bob

I was able to resolve my issue. These are the steps that were different in my successful attempt: 1) When creating the self signed cert, I passed the date parameters in MM/DD/YYYY format, and added the -String.Previously I was passing the date as DD/MM/YYYY. The snippet I ran was as follows: .\Create-SelfSignedCertificate.ps1 -CommonName "cwl-partner-pack" -StartDate 09/11/2016 -EndDate 09/11/2018 -Password(ConvertTo-SecureString -String "foo" -AsPlainText -Force) 2) My VS2015 was signed in under my microsft account registered with MSDN, which is not the subscription I was working with. To make sure I was targeting the right subscription, I signed out of visual studio (top right) and in the cloud explorer I connected to the target subscription. 3) This is the one I think that was the fix. When I ran the publish dialog, I imported the publishing profile, but instead of publishing I click on "Close" (next to publish). Then I ran the publish dialog again, and this time the "Enable Organizational Auhtentication" option appeared, and was checked off. I unchecked it, then published with successful outcome. Bob

Did you add the certificate to your Azure web app as described here: https://github.com/OfficeDev/PnP-Partner-Pack/blob/master/Documentation/Manual-Setup-Guide.md#app-only-certificate-configuration-in-the-azure-web-app?

  Yes I completed the steps to create the x.509 self signed certificate and uploaded it to my web app, as per the instructions. I also added the "WEBSITE_LOAD_CERTIFICATES" with value of "*" to the App Settings area. I used the latest PNP-Powershell from github to create the cert, extract the Key information, paste into the manifest and upload back into the Azure AD App configuration.
  
  Other details:
  
  - added the "/" at the end of the reply to address in the Azure AD app configuration
  - for the Azure AD app, added the app permissions for SPO and delegate permissions for Microsoft Graph (read and write access to USer Profiles) FYI I missed this on the first attempt.
  - When generating the secret for the Azure AD app, I specified two years instead of one.
  - creation of Infrastrucutral Site, provisioning of Infrastructral site, and web.config customization were completed successfully using the powershell scripts.
  
  I was follwing the video, which obfiscates some of the powershell text when creating the cert. Here is what I used to create the cert, perhaps thats an issue.
  .\Create-SelfSignedCertificate.ps1 -CommonName "mysiteprovisioning" -StartDate 06/09/2016 -EndDate 06/09/2018 -Password(ConvertTo-SecureString "xxxxxx" -AsPlainText -Force)
  
  I did make three attempts. Each time I deleted the Azure AD app, the web app. and the infrastructual site collection in my tenant. I was careful to isolate certs, Client IDs, etc. between each attempt. Each time I landed on this error on page load:
  
  Oops! Exception occurred!
  Value cannot be null. Parameter name: certificate

    One last thing to doublecheck is how you've published the web app...from the guide: "When you publish the web application, remember to *uncheck *the option "Enable Organizational Authentication". If you leave this selected you migh face authentication issues when running the pnp-partner-pack"
    
    I've specifically addded that to the docs as I was having similar issues like you're seeing when I deployed the partner pack.
