Ingest data with a pipeline in Microsoft Fabric - Create a Pipeline

DataUnicorn — Thu, 20 Nov 2025 03:39:39 GMT

Hi,

I'm on this exercise https://microsoftlearning.github.io/mslearn-fabric/Instructions/Labs/04-ingest-pipeline.html#create-a-pipeline but I don't seem to be able to select the new_data folder as a location to store the sales csv. Would someone know why I'm getting this error message?

The new_data subfolder has already been created

Hi @DataUnicorn,

I've encountered the same issue before, In my case, the problem came from a invalid connection in the pipeline.

Here’s what worked for me:

Go to the destination step in your pipeline.
Delete the existing connection that points to the Lakehouse.
Create a new connection and reconfigure the destination.

After recreating the connection, the pipeline ran normally again.

Thanks Antoine,

Just to give you an update, I've tried recreating the destination but I still receive the same error. So I deleted the activity and started from scratch again but now I'm facing the error below. I think I will try deleting and recreating again.

Hi @DataUnicorn ,

After deleting and recreating again, are you still facing any issues?

Thank you.

Hi, unfortunately I am. This is what's happening now. I've recreated the connection. still didn't work so I went to connections and tried to log in again but it doesn't like my credentials. But its the same account i used when I created the connection. I don't have any other accounts.

Hi @DataUnicorn,

Thank you @AntoineWm, for your insights.

Delete the faulty Lakehouse connection from Settings Manage connections and gateways. Create a new Lakehouse connection using the Copy Data activity and sign in with your Microsoft account. Once you see the green check mark, set the destination path to Files/new_data/sales.csv and confirm you have Member or Admin permissions in the workspace. After authentication is restored, you’ll be able to browse folders normally and select the new_data folder in the pipeline without errors.

Thank you.

Hi,

I've just tried this and it's still giving me the same issue. I'm the workspace admin. SO when I create the connection, it accepts my credentials.

But when I try to browse the location, it comes up with the same error

Hi @DataUnicorn,

Since the issue persists even after recreating the Lakehouse connection and verifying your workspace permissions, it is likely a backend issue. Please submit a Microsoft Support ticket so the engineering team can review the activity ID and workspace logs.
