Azure function deploy error using MSDeploy in Bicep file

Question

Azure function deploy error using MSDeploy in Bicep file

Valeria Naldi 145

I'm using a bicep file to deploy Azure resources, among them a FunctionApp and 3 Functions

FunctionApp deployment works fine.

I'm deploying Functions using a zip file created from the "Download app content" button on a previously created FunctionApp and Functions and uploaded on a git repository

This is the bicep content:

resource funcAppDeploy 'Microsoft.Web/sites/extensions@2020-12-01' = {
  parent: funcApp
  name: 'MSDeploy'
  properties: {
    packageUri: funcPackageUri
  }
}

where funcPackageUri is like this

var funcPackageUri = 'https://github.com/<repoorg>/<reponame>/raw/main/<foldername>/funcapp-deploy.zip'

I have this error during the deployment:

{"code":"Failed","message":"ARM-MSDeploy Deploy Failed: 'Microsoft.Web.Deployment.DeploymentDetailedException: Object of type 'package' and path 'C:\local\Temp\f5e1b1e4-1a43-4567-95d7-d4ae670fd17f.zip' cannot be created.

Can you please help me to understand what is wrong?

Hello, @Valeria Naldi - Thanks for reaching out! The error ERROR_EXCEPTION_WHILE_CREATING_OBJECT indicates that the MSDeploy wasn't able to access the zip file hence not being able to recreate it in the C:\local\Temp\f5e1b1e4-1a43-4567-95d7-d4ae670fd17f.zip directory. I suspect that the root cause could be either an access issue when downloading or a permission-related issue on the filesystem. It's also a best practice to set appOffline to true when using MSDeploy.

On another note though, I highly recommend that you move away from MSDeploy and switch to ZipDeploy along with RUN_FROM_PACKAGE app setting instead as this is the official recommendation by the Functions team. Here's the official sample for ARM template with ZipDeploy:

Function App Deployment with ZipDeploy Run From Package

If you're hesitant about using ZipDeplooy, here are some links that might help:

I hope this answer helps. If you have any further questions, feel free to follow up in the comments ;)

Thank you for the quick reply.

How can I verify if I have permission problems? I'm a Co-Administrator of the subscription where I'm working on

I tried using the ZipDeploy

resource funcAppDeploy 'Microsoft.Web/sites/extensions@2022-09-01' = { parent: funcApp name: 'ZipDeploy' location: location properties: { packageUri: funcPackageUri } }

and added

{ name: 'WEBSITE_RUN_FROM_PACKAGE' value: '1' }

to the FuncApp deployment.

Now I have a different error:

{"code":"ResourceDeploymentFailure","target":"/subscriptions/<subId>/resourceGroups/ValeriaTest-rg/providers/Microsoft.Web/sites/funcapp-d46b9bb7/extensions/ZipDeploy","message":"The resource write operation failed to complete successfully, because it reached terminal provisioning state 'Failed'."}

Note: using the same zip file, I'm able to deploy the functions with the " az functionapp deployment" CLI

Note2: using ZipDeploy on the bicep file I have this warning:
Warning BCP088: The property "name" expected a value of type "'MSDeploy' | 'onedeploy'" but the provided value is of type "'ZipDeploy'". Did you mean "'MSDeploy'"?

@Valeria Naldi Sorry for the late reply. That appears to be a support issue within the Bicep and it looks like the following workaround can be used for now:

resource deploy 'extensions@2022-03-01' = { name: any('ZipDeploy') properties: { packageUri: servicePackageLink } }

Please see: https://github.com/Azure/bicep-types-az/issues/1632

Yes, I saw the workaround using any('ZipDeploy'). It removes the warning but the error for me is always the same

The resource write operation failed to complete successfully, because it reached terminal provisioning state 'Failed'. (Code: ResourceDeploymentFailure, Target: /subscriptions/936a9bcb-9188-44fb-8b80-1530a7cd9bb4/resourceGroups/ValeriaTest-rg/providers/Microsoft.Web/sites/funcapp-1a28d0a6/extensions/ZipDeploy)

Any idea about this error?

Thanks again

Additional notes: I found these two issues that seem the same

https://github.com/projectkudu/kudu/issues/3041

https://github.com/microsoft/azure-pipelines-tasks/issues/11444

The second is reported as closed, but the last comment says it is still open. Looking at the console of my function app I can see the same errors in the wwwroot folder

C:\home\site\wwwroot>cat 'FAILED TO INITIALIZE RUN FROM PACKAGE.txt'
Run From Package Initialization failed.

C:\home\site\wwwroot>cat web.config
<?xml version="1.0" encoding="UTF-8"?>

@Valeria Naldi If you're still hitting the same error even after attempting to use the official samples provided in my answer above, feel free to proceed to open a support case for this issue as the next step. If your Azure Subscription doesn't carry a support plan, let me know in your reply and I'll help grant your subscription a one-time free support support for resolving this particular issue.
