Hi, In ā€œStep 6.3. Visualize the Data IIā€ Iā€™ve created my visualisations component with the appropriate graphs but get an error when trying to view the output - ā€œTypeError: Unable to get property ā€˜initā€™ of undefined or null reference at Global Code (Unknown script code:1:36302)ā€

This also happens in the solution workflow so itā€™s not related to anything Iā€™ve done in configuring my component.

In both the solution and my version of the workflow, if I go into the component I can successfully view each graph individually.

Iā€™m using Knime 5.2.5 on a Windows 10 PC. Any thoughts as to why this is happening ?

Thanks ! Drew

Hi @DrewG42 did you manage to solve your problem eventually? If not, do you only have issues with that specific component, or can you not see any composite views?

I cleared my first hurdle: Where to find the Table Reader node

I searched and couldnā€™t find!
(I had ignored the hint because I wanted to do it from first principles.)
I followed the links to find info about the node, but eventually, I noticed the search boxā€™s message:

I still didnā€™t figure it out immediately, but the answer was within the Preferences settings:

Iā€™m sharing my mini-journey into rookie mistakes so it might help someone else. Happy KNIME-ing!

Hello,

Iā€™ve just started working through the first course, and it references Example Workflows. In the course, Iā€™m directed to the folder The Data and then Basics. However, this folder is completely missing on my system. I canā€™t seem to find where to download it or how to add it to my environment.

Could someone please assist me in finding the complete Example Workflow folder so I can properly follow along with the courses?

Thank you!

By default, there should be a file at C:\Program Files\KNIME\knime-workspace.zip, but if KNIME was installed to your user directory, then it would be in AppData\Roaming\KNIME

Are you looking at the knime-workspace that you set up the very first time you ran the Analytics Platform (AP)? You can change by clicking on the Menu button at the top right, and then selecting ā€œSwitch workspaceā€. When the modal comes up, it should show you recent workspaces and one of them should be called kinme-workspace.

I have accidentally dismissed the three example workflows on the entry page (modern UI). It says in the manual that to restore the examples, click Help > Restore examples on home tab, but I cannot find this option under the Help buttonā€¦ What am I supposed to do?

Hi! Iā€™m working through the course to get a better understanding of using Knime. Iā€™m on the 5.2 question of the hands on activity. Iā€™m having trouble getting the configuration correct to determine basket size. Would anyone be able to share the correct settings in the configurator? Also, I just want to verify that I have the join set up correctly from the previous step, but would someone be willing to share that configuration as well? Thanks!

Hello! I am also at this stage of the beginnerā€™s course and have the same question regarding how to configure the configuration box to show basket size in the GroupBy. If anyone has this information or can help me, I would gratefully appreciate it. Many thanks in advance.

Hi,

I have a Question regarding Data Access if I want to extract data from GitHub Repo, Kaggle, Oracle Apex or other cloud system. How can I fetch data from these platform. I have a request can you make or arrange a webinar related to Data Access Module, it will be very beneficial for us.

Thank You

Hi @sheetal08!
Thanks for your proposal about the webinar, Iā€™ll forward it to the team.

Addressing your other questions:

  1. To access data from GitHub or Kaggle I think the most straight-forward solution would be to make use of their REST APIs. In KNIME, to issue HTTP requests you can use the nodes of the KNIME REST Client Extension
  2. To access databases (for example Oracle) you can make use of the KNIME Database Extension. This extension provides nodes to connect to any JDBC-compliant database.
  3. And to connect to cloud systems you can make use of the dynamic handling. Check out the KNIME File Handling Guide

There is lots of docs out there that teach these things and Iā€™m sure also on the Forum youā€™ll find a lot of threads around these topics.

FYI: All these topics are addressed in the L2 courses we offer :slight_smile:
