Dataflow Error - fileUri.Segments.Length >= 4
I am receiving the following error when trying to save a Dataflow:
An invalid ADLS Gen2 uri has been received: 'AdlsFileSystemManager.ValidateFileUri => fileUri.Segments.Length >= 4 [https://REMOVED.dfs.core.windows.net/commondataservice-REMOVED-orgREMOVED/model.json]'.
Steps to replicate:
- Navigate to a Dynamics environment in PowerApps and complete the "Export to data lake" wizard
- Navigate to the Power BI Service and attach the above model.json (generated in step 1) using "Attach a Common Data Model folder (preview)". Note: this step works fine - I am able to query the results in PBI Desktop.
- Create a new dataflow containing a Linked Entity from the above dataflow (generated in step 2).
- Try to save. The error will appear.
The error message suggests we cannot have URI segments greater than 3. This does not make sense given that when you click "Attach a Common Data Model folder (preview)" the example has 4: https://myaccount.dfs.core.windows.net/filesystem/path/model.json
Any thoughts on a solution?

Hi Anonymous ,
You may go through “Connect ADLS Gen2 for dataflow storage” and see if you are missing any steps.
Thanks v-frfei-msft, unfortunately that link is unrelated. At no point do I export to a custom ADLgen2, my issue is import related and therefore that tutorial does not apply.
