Can't create azure linked service with python

Question

What I'm trying to do

I'm trying to create an azure data factory pipeline to copy and paste file from a blob to a blob or from a blob to a data lake.

What i did

I just followed the tutorial on Microsoft's website, i already have an ADF and blob so i didn't create it again, i'm now trying to create an Azure linked service, so i used this code:

# Create an Azure Storage linked service
ls_name = 'storageLinkedService'

# IMPORTANT: specify the name and key of your Azure Storage account.
storage_string = SecureString('DefaultEndpointsProtocol=https;AccountName=<storageaccountname>;AccountKey=<storageaccountkey>')

ls_azure_storage = AzureStorageLinkedService(connection_string=storage_string)
ls = adf_client.linked_services.create_or_update(rg_name, df_name, ls_name, ls_azure_storage)
print_item(ls)

But when i run it, i obtain this error:

Traceback (most recent call last):

  File "<ipython-input-173-cabc65dd11b9>", line 4, in <module>
    ls = adf_client.linked_services.create_or_update(rg_name, df_name, ls_name, ls_azure_storage)

  File "C:\ProgramData\Anaconda3\lib\site-packages\azure\mgmt\datafactory\operations\linked_services_operations.py", line 170, in create_or_update
    raise models.ErrorResponseException(self._deserialize, response)

ErrorResponseException: Operation returned an invalid status code 'Not Found'

I don't know why do i get this error. Does anyone have an idea ?

Update

I tried to skip this step and tried to create and file in the blob with this command: adf_client.datasets.create_or_update(rg_name, df_name, ds_name, ds_azure_blob)

I got the same error ErrorResponseException: Operation returned an invalid status code 'Not Found' which lead me to think that the problem is related to the blob maybe.

Answer 1

I tried to reproduce your issue but failed.

I do not have an ADF so I followed the official tutorial to create Data Factory and Linked service, no error occurred.

main function

def main():

    # Azure subscription ID
    subscription_id = '***'

    # This program creates this resource group. If it's an existing resource group, comment out the code that creates the resource group
    rg_name = '***'

    # The data factory name. It must be globally unique.
    df_name = '***'

    # Specify your Active Directory client ID, client secret, and tenant ID
    credentials = ServicePrincipalCredentials(client_id='***', secret='***', tenant='***')
    resource_client = ResourceManagementClient(credentials, subscription_id)
    adf_client = DataFactoryManagementClient(credentials, subscription_id)

    rg_params = {'location':'eastus'}
    df_params = {'location':'eastus'}

    # create the resource group
    # comment out if the resource group already exits
     resource_client.resource_groups.create_or_update(rg_name, rg_params)

     Create a data factory
     df_resource = Factory(location='eastus')
     df = adf_client.factories.create_or_update(rg_name, df_name, df_resource)
     print_item(df)
     while df.provisioning_state != 'Succeeded':
         df = adf_client.factories.get(rg_name, df_name)
         time.sleep(1)

    # Create an Azure Storage linked service
    ls_name = 'storageLinkedService'

    # IMPORTANT: specify the name and key of your Azure Storage account.
    storage_string = SecureString('DefaultEndpointsProtocol=https;AccountName=***;AccountKey=***')

    ls_azure_storage = AzureStorageLinkedService(connection_string=storage_string)
    ls = adf_client.linked_services.create_or_update(rg_name, df_name, ls_name, ls_azure_storage)
    print_item(ls)

ErrorResponseException: Operation returned an invalid status code 'Not Found'

I think you could check the arguments if you have a mistake in it or if the service exists.(df,resource group, storage account)

Any concern ,please feel free to let me know.

Update Answer:

I created my own application registration in Azure AD on portal.

Application ID as below is your client_id

Create your secret and remember to write it down because it will hide later.

Directory Id as below is tenant ID

Update Answer 2:

I'm also a contributor role, so I think it's not a role issue. I tried to change the ra_name(resource group) in the parameter to a nonexistent value, reproduced your exception successfully .

Please check again if your resource group or other parameters exist.

Just for summary:

It seems that ADF V1 and V2 does not support West Europe Region currently.

However , the Supported regions chapters in this article have not been updated. That bothers you so long. You could re-create ADF and follow your original code to create link service.
