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

[amien]

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-dat... 

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.

@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.

 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.
