Azure-docs: Parametrizing Blob Storage Linked Service Is Not Working

[mirsaeedi]

I tried to parameterized a blob storage linked service manually through the code editor.

{
    "properties": {
        "type": "AzureBlobStorage",
        "annotations": [],
        "typeProperties": {
            "connectionString": "DefaultEndpointsProtocol=https;AccountName=@{linkedService().Path};EndpointSuffix=core.windows.net;",
            "encryptedCredential": ""
        },
        "parameters": {
            "Path": {
                "type": "String"
            }
        }
    }
}

I pass the parameter value from the pipeline to the dataset and eventually to the linked service. The issue is that the linked service cannot capture the parameter value and it's always empty. I get this error upon running the pipeline that is using this linked service:

{code":"BadRequest","message":"No value provided for Parameter 'Path'","target":"pipeline/Delete files with Azure Data Factory/runid/1c29b7ba-36d2-4f38-a569-e381f33c8269","details":null,"error":null}

Can you post this question on our MSDN forum? Github issues are generally for doc related bugs or improvements

[mirsaeedi]

I thought it might be a bug because in the document it had been mentioned that it's possible to paramterized linked servers through the code editor.

[djpmsft]

You can parameterize linked services through the code editor. The MSDN forum will allow our customer experience team to investigate the issue and determine if the doc is misleading or not.

The issues looks to be in the passing of the parameter from the linked service, rather than the linked service definition
