Ontology error in tutorial : Duplicate property name 'freezerd' found. Property names must be unique

I'm trying to follow this tutorial, but i run into an issue which i can't fix somehow

 

I'm at this step: 

 

https://learn.microsoft.com/en-us/fabric/iq/ontology/tutorial-2-enrich-ontology#bind-time-series-data-to-additional-properties 

 

 

I get this error: Duplicate property name 'freezerd' found. Property names must be unique across both Properties and TimeseriesProperties within the entity type.

 

I tried to rename the FreezerId from "freezerId" into "FreezerId" in the FreezerTelemetry.csv file. But that gave me the same error.

 

Has anyone run into this issue as-well and fix it? please share

    amien nielsvdc I confirm that after recent updates the Ontology tutorial now works. Keep in mind, that it's still limited to using a Lakehouse without a schema only otherwise the Ontology preview does not work. We'll keep an eye on the next updates in Ontology.

     Hi amien, this evening I was unable to completely run through the tutorial, as generating the ontology kept failing. But could it be that you misconfigured something in the previous steps in this page?

     

    I will try creating the ontology again tomorrow and see if I ran into the same problem.

     

    Hope this helps. If so, please give a Kudos 👍 or mark as Accepted Solution ✔️.

        Good to hear! On my side Ontology is unfortunately still refusing to work, so I'll have to wait. Have fun discovering this new feature.

    amien thanks for pointing out there is an Ontology tutorial. I recently did a tutorial for Ontology in Real-Time Intelligence training. So far, in my opinion, this is a very early stage of this feature. I think it will take some time before everything works as intended. But great seeing community's interest. I am interested in seeing how you progress through that tutorial. I have a request from my user group to present about the Fabric IQ and Ontology feature.
