When using a clean Data Pipeline and trying to Copy Data using the Copy Assistent, I can't view anything from the OneLake catalog.
It displays an error stating: "Something went wrong. Please try again".
When looking into my OneLake list from the menu on the left, I have a nice collection of items.
Admitted, I'm new to MS Fabric and I'm just following the tutorial (which isn't too accurate probably due to updates to the UI). The step I'm trying to do is the Lakehouse introduction, step 4: Ingest data.
I'm trying this out in order to potentially recommend this to my employer organisation but the issue doesn't look too good.
Anyone who can help me?

Hi @zapan ,
Thanks for using Microsoft Fabric Community Forum.
The issue you are facing might arise from multiple factors.
1> Ensure that your account has the required permissions to access the OneLake catalog. You need to have at least Contributor access to the workspace containing the OneLake items.
2>Microsoft frequently updates Fabric. Ensure you’re using the latest features and fixes by refreshing your browser and clearing its cache.
3>Clear Cache and Cookies to avoid any conflicts.
Alternately you can ingest data by using pipeline activity as shown below:
1. Select Pipeline activity instead of Copy assistant and select copy data from the drop down.
2. Then in the canvas a copy data activity will be added as below.
3. Now you can select the Connection under Source where different data sources populate for you to select.
You can also use Data Flows and Notebooks in Lakehouse to ingest and transform data.
Please reach out if you need assistance further. We are happy to help.
Hope this helps.

Thanks @v-veshwara-msft. The manual steps made the difference. Though I can't make the Wizard work.
