Azure Logic App deployment via Powershell - azure

Question

I have developed a powershell script that allows me to download the Logic Apps from the portal in Visual Studio. Along with the JSON template it also downloads the parameters defined in the Logic App (which is how I wanted). We had established connections with Dataverse and Salesforce via Sign in method. But the problem is that when I download the template via Powershell script and update the parameter file to deploy to a different environment it asks for the credentials which are for service principal login. I haven't used service principal login when creating the connection and I don't have those credentials. I tried removing those parameters from both the parameter file and .JSON file but I am getting error as below:
Error: Code=InvalidDeploymentParameterValue; Message=The value of deployment parameter 'commondataservice-5_token:clientSecret' is null. Please specify the value or use the parameter reference.
These parameters were automatically added in my parameter.json file.
"commondataservice-5_token:clientId": {
"value": null
},
"commondataservice-5_token:clientSecret": {
"value": null
},
"commondataservice-5_token:resourceUri": {
"value": null
},
"commondataservice-5_token:grantType": {
"value": "code"
}
This is how the main Logic App template looks like for the dataverse connection
{
"type": "Microsoft.Web/connections",
"apiVersion": "2016-06-01",
"location": "[parameters('logicAppLocation')]",
"name": "[parameters('commondataservice-5_name')]",
"properties": {
"api": {
"id": "[concat('/subscriptions/',subscription().subscriptionId,'/providers/Microsoft.Web/locations/',parameters('logicAppLocation'),'/managedApis/commondataservice')]"
},
"displayName": "[parameters('commondataservice-5_displayName')]",
"parameterValues": {
"token:clientId": "[parameters('commondataservice-5_token:clientId')]",
"token:clientSecret": "[parameters('commondataservice-5_token:clientSecret')]",
"token:TenantId": "[parameters('commondataservice-5_token:TenantId')]",
"token:resourceUri": "[parameters('commondataservice-5_token:resourceUri')]",
"token:grantType": "[parameters('commondataservice-5_token:grantType')]"
}
}
}
Below is the Powershell command to get the LA template:
Get-LogicAppTemplate -LogicApp fc-cus-dev-int-test-param-dynamicexpression -ResourceGroup FC-CUS-DEV-INT-RG -SubscriptionId xxxxx-xxxxxx -Verbose | Out-File "C:\Users\xxxxxx\Desktop\DynamicExpression-NA.LogicApp.json"
#Powershell command to get the Parameters:
Get-ParameterTemplate -TemplateFile "C:\Users\xxxxx\Desktop\DynamicExpression-NA.LogicApp.json" | Out-File "C:\Users\xxxxxx\DynamicExpression-NA.LAparameters.json"
I have followed this article to download the Logic App: https://blog.sandro-pereira.com/2020/12/21/logic-apps-moving-from-azure-portal-to-visual-studio/
I am having a hard time trying to remove the connection parameters from the parameter file and deploying the LA. Any suggestions or pointers are highly appreciated

You have to update the parameter file with actual values. When you extract a template it creates the parameter file but for for security reasons any value that should not be public (i.e. password) it does not retrieve the existing value. Those values all show as null in your parameter file. You need to get those values and update the parameter file before deploying.
