Below is my Parameters.Json file:
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"Vault_name":"KVCheck",
"secretsObject": {
"value": {
"secrets": [
{
"secretName": "Test1",
"secretValue": "Sample Value"
},
{
"secretName": "Test2",
"secretValue": "Sample Value"
}
]
}
}
}
}

and here is my Template :

{

"contentVersion": "1.0.0.0",
"parameters": {
"Vault_name": {

}

"secretsObject": {

}
}

"count": "[length(parameters('secretsObject').secrets)]"
},
"properties": {
"value": "[parameters('secretsObject').secrets[copyIndex()].secretValue]"
}
}
]
}
and its not able to recognize the object.

Open the linked 201-key-vault-secret-create template and inspect the secretsObject parameter and the Microsoft.KeyVault/vaults/secrets resource at line 73. Reproduce the deployment with the supplied Parameters.Json; done means the template validates and deploys the listed Test1 and Test2 secrets without the reported property error.
