No Enum Constant Error on Table Reader

[Vettel]

Hi Guys,

I am a total newbie on Knime and started to learn the basics. Tried doing EXAMPLES- 50 Applications-28 Prediction Delays(all of them). Downloaded the extensions that Knime suggested.

When I try to execute the whole system, there is an error consisting of “0:732:731 Execute failed: Unable to read meta information from file. Unable to parse “container.compression” property (“Gzip”): No enum constant org.knime.core.data.container.DefaultTableStoreFormat.CompressionFormat.GZİP”

My workspace’s in C:Users, Main Folder’s in C:Program Files. Downloaded KNIME Analytics Platform for Windows (installer) 64 bit.

What I should do?

Can you help me getting through with this?

Hi @Vettel,

welcome to the community, sorry for your inconveniences and the late response.

I’m already looking into the issue. I assume you’re running KNIME 4.0.2?

As I assume it is urgent that you can run that workflow. To do so, you could download the data from the website given in the annotation and read them in via the File Reader node. This video might be helpful Data Access in KNIME.

Yes, I am running Knime 4.0.2, that’s correct.

Same error on Examples- 01 Data Access-01 Common Type Files-06 Table Reader and Example Workflows-Retail-Finding Association Rules for Market Basket Analysis.

I am waiting for your response. Thank you very much.

Hey @Vettel,

we are unable to reproduce the problem locally.

Could you please just run the table reader again and sent us the relevant part of your KNIME log ( View -> Open KNIME log).
