I recently updated knime to 4.3 and had lots of problems trying to download the Tableau extension. After trying many solutions of old topics without results I went to a Knime 4.2.3 version that was appointed by the company I work.
Ok, after that and using the HTTP:// (without the “S”) on the extension sites trick I was able to download and install the extension to my knime. Problem solved, right? NOT
The extension seems fine but simply doesn’t work. I tried a bunch of stuff from older topics without any results. Tried even to use the legacy version of the extension but it doesn’t work anymore either.
These are the error messages
The first time I try to run the newer extension I get this:
Hi Zack! sorry for the delay. I’ve been overwhelmed by work and I’m using Tableau prep as solution while this node doesn’t function
answering in bold your questions :
What version of Knime 4.3 did you upgrade to? I don’t know what do you mean by version. I went to Knime webpage and got the windows 64 file
Do you experience the same error messages you sent us screen shots of in 4.3, or these are only from 4.2.3? No. In the 4.3 I couldn’t download the extension even after trying every solution I’ve found online. Only on 4.2.3 that the removing the S in HTTPS solution worked
How did you install the extensions in 4.3/4.2.3, did you drag and drop or did you download directly from Knime AP? I dragged from the extension page
What were the errors you were seeing when you were having trouble downloading the Tableau Extensions in 4.3? Sorry, I can’t remember what exactly happened but as far as my memory goes it was something like a error message that the extension page could not be accessed
Can you send us a screen shot of your configuration of the Tableau Writer nodes? You can blur out any sensitive data. This node doesn’t have any configuration. You just select how it will handle cases where the file to be saved already exists. I’m not using any variable so everything is on default
The error messages I posted doesn’t give any clue about why the node is not working?
On the question 4: I’ve just remembered that on 4.3 after the “S” removal solution the extension was found but the installation failed. Can’t remember the reason though. I went back for an early version because before I upgraded the extension was working fine
Would you be able to turn on debug logging in the KNIME AP platform and re-create the issue from the 4.3 version? To do this you would go to Preferences → KNIME → Check the debug radio button.
Then re-create the error, and send us the log files?
Could you also go into the Help → Install New Software → Then in the configuration window click on “whats already installed” hyperlink, and type in Tableau, and provide us with the version and ID information that is displayed?
Then could you click on the Tableau extension and click the uninstall, and then restart, and then try to re-install and see if you get the same error messages?
Can you please also confirm that system property jna.nosys=true?
If this does not help would you mind also emailing support@knime.com and we can have a Zoom call to troubleshoot this together?
