### Issue Details

Error parsing template. Please ensure template is valid JSON and has no comments.

I would like to add the template to Azure-quickstart-templates, but somehow I get errors.
### Repro steps (_if necessary, delete otherwise_)
1. Using the deploy mechanism to deploy the template.
2. tested the files with a JSON validator

Start by reviewing the linked azure-caddy-wordpress repository and reproducing the deployment mechanism described in the issue. No specific file or test is named; done means identifying why the template parser rejects the submitted template and confirming that the corrected template deploys successfully.
