Deploy to serverless Azure Functions Failed

Question

I'm trying to deploy Azure Functions in already created App Service in Azure portal.

Using sls deploy CLI for deploying my Azure function, but while deploying the functions sls is trying to create new resource group for which I don't have access.

Following is the output of sls deploy command:

$ sls deploy
Serverless: Removing .serverless directory

     Components Version:        2.30.11

In serverless.yml, I've also specified the resourceGroup parameter. Here is the gist of serverless.yml

provider:
  stage: dev
  name: azure
  region: East US 2
  runtime: nodejs10.x
  resourceGroup: <ALREADY_CREATED_RESOURCE_GROUP_NAME>
  subscriptionId: <SUBSCRIPTION_ID>

Is there any way to set resource group in serverless cli which can be used while deploying the functions?

From the error message, looks like the service principal / user trying to execute this doesn't have permission to create resources, isn't it? Probably should be a contributor. there is a similar question here [stackoverflow.com/a/37689720/5344880] with accepted answer. hope it helps — Guru Pasupathy
Not looking to create a resource group. Only want to deploy my functions under an App Service. — Parag Jadhav
@ParagJadhav I agree with Guru, you should check the subscription permission of the service principal or user you used to deploy the function. — Tony Ju
@TonyJu I have a contributor access to the function that I'm sure of. I can even deploy the function in the current app service if I generate a new project template using Azure Function extension in VS Code. Please let me know if you want me to update the question with more granularity — Parag Jadhav

I was able to deploy the Azure functions by breaking down the deployment in two parts

Package the project using serverless.
```
sls package
```

Deploy the packaged zip file using Azure CLI.

az functionapp deployment source config-zip -g {RESOURCE_GROUP} -n {APP_SERVICE_NAME} --src .serverless/project-zip.zip

Hope this helps someone who is facing the same issue.

Edit:

Looks like this issue might get resolved in upcoming releases.
