Start with azuredeploy.json and azuredeploy.parameters.json, then inspect the nested template links reported in the deployment error, including nestedtemplates/master-nodes-resources.json and the other listed resources files. Run the provided New-AzResourceGroupDeployment command and verify that the referenced deployment content can be retrieved and validation completes without InvalidContentLink errors.
