question about deploying app service in asdk

I am having some problems deploying app service I used a template from github (https://github.com/Azure/AzureStack-QuickStart-Templates/tree/master/appservice-fileserver-sqlserver-ha) to install all the resources. and it failed just on provisioning the sql vm with the "sql iaas extension" it just says "conflict"
so i redeployed just the vm with the issue and it succeeded but there is nothing displayed in the deployment output
so when it comes to running the app service resource provider installer application i am missing some information to complete the deployment. and I am having problems when running "Create-AADIdentityapp.ps1" It can't find the directory of the sso certificate even though i have double and triple checked the full path is correct. I am not sure if it is necessary to run the certificate validation module. I hope my ramblings make sense to someone. thank you!
