Logic App queue trigger (In-App) not firing when connections.json contains the connectionString value

[ppanchal-mobiz]

Describe the Bug

When the connections.json file contains the connectionString value instead of the appsetting reference, the following error is logged in the Host log file. The error says validation and creation failed but that Azure portal saves it successfully and the workflow is not triggered instead.

Workflow Error: operationName='WorkflowFunctionDefinitionProvider.ProcessWorkflow', message='Workflow 'queue-trigger-temp' validation and creation failed. Error: 'The template validation failed: 'The provided value 'DefaultEndpointsProtocol=https;AccountName=<redacted>;AccountKey=<redacted>;EndpointSuffix=core.windows.net' is not template language expression. (Parameter 'expression')'.'', exception='Microsoft.Azure.Workflows.Common.ErrorResponses.ErrorResponseMessageException: The template validation failed: 'The provided value 'DefaultEndpointsProtocol=https;AccountName=<redacted>;AccountKey=<redacted>;EndpointSuffix=core.windows.net' is not template language expression. (Parameter 'expression')'.

erroneous connections.json file:

{
    "serviceProviderConnections": {
        "azurequeues": {
            "displayName": "architectapplasa",
            "parameterSetName": "connectionString",
            "parameterValues": {
                "connectionString": "DefaultEndpointsProtocol=https;AccountName=<redacted>;AccountKey=<redacted>;EndpointSuffix=core.windows.net"
            },
            "serviceProvider": {
                "id": "/serviceProviders/azurequeues"
            }
        }
    }
}

fix required for workflow to trigger:

{
    "serviceProviderConnections": {
        "azurequeues": {
            "displayName": "architectapplasa",
            "parameterSetName": "connectionString",
            "parameterValues": {
                "connectionString": "@appsetting('azurequeues_connectionString')"
            },
            "serviceProvider": {
                "id": "/serviceProviders/azurequeues"
            }
        }
    }
}

Plan Type

Standard

Steps to Reproduce the Bug or Issue

1. Create a new stateful workflow in Logic App Standard using the Azure portal
2. Select When messages are available in a queue as the trigger
3. Create a new queue connection using Storage account connection string as the Authentication Type
4. Provide the Storage Account Connection String
5. Save the workflow and ensure the connection string value provided in step-4 is stored in connections.json file.
6. Put a message in the queue and check if the workflow is triggered.
