Azure function with docker image throwing throws missing connection string error even though present

Question

I have a custom docker image that I am trying to run azure functions on and I managed to get the function running but the code throws the following error

: Host.Startup[515]
      A host error has occurred during startup operation '48758bfd-0fc4-4ac1-bcba-042a0338e561'.
System.InvalidOperationException: Microsoft Azure WebJobs SDK ServiceBus connection string 'analysis_SERVICEBUS' is missing or empty.

On my local.settings.json I have already specified the connection string

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=false",
    "FUNCTIONS_WORKER_RUNTIME": "node",
    "UI_URL": "http://localhost:8080/report/",
    "analysis_SERVICEBUS": "my connection string is listed here "
  },
  "Host": {
    "LocalHttpPort": 9991,
    "CORS": "*",
    "CORSCredentials": false
  }
}

Is there something more that I need to do with my docker image to make the code run?

Answer 1

In your json configuration, you have analysis_SERVICEBUS nested under Values. It should be in the root of the json.

{

    "analysis_SERVICEBUS": "Endpoint=sb://xxxx="

}
