Iâm encountering an error with the JSON Path node while trying to work on Hands-on Exercise - Part 4, specifically the 04_Part1_GET Request exercise workflow.
The error persists even when using the provided solution workflow. Although the workflow execution is successful, Iâm unable to access the configuration of the JSON Path node in the solution workflow.
Found a solution: the GET request node wasnât actually receiving any data. Selecting the âTrust all certificatesâ checkbox seems to solve the problem.
Hello, I have a problem on the L2 DA part 1 Flow variables and component exercise, I already finished L1 basic proficiency and want to continue on this but i do not know what you mean by " From the output table of the Processed Customer Data metanode, use the Row Aggregator node to find the total sale for each store. Use StoreID as the category column, and aggregate the sum of the column Price. WHERE is that table, I can not find it. Is there a table named processed customer data?
After that you use the Row Aggregator node to find the total sale for each store. Use StoreID as the category column, and aggregate the sum of the column Price.
@Andrei_Avram do you mean that you canât run the metanode? If yes, you donât need to open it. Just hover over it until the Execute button appears on the top and click on it. Does this help?
On the screenshot that you sent it is being executed. Does it never get to the executed state? Could you please send the screenshot of whatâs happening inside? Double click on the metanode to open the workflow inside.
If you click the Execute button, the content of the metanode should get executed. On the screenshot you sent, it looks like the Execute button wasnât clicked. You can also try to click Execute all button inside of the metanode.
Hi all!
I am following the L2-DA course. As I still have a version of KNIME <5 I have issues to open the Exercise workflows. Is there a version of the course exercises compatible with KNIME <5? Thx
Happy to see that youâre interested in the course. The L2-DA course was created in version 5, therefore, we donât have the previous version of the exercises for this course. A similar course that we used to have in versions <5 was L2-DW. The content of that course also differs from L2-DA (not drastically, but they arenât completely aligned). You can try to check the L2-DW exercises here: knime/Education â °Legacy courses° â KNIME Community Hub and in case you also want to follow the legacy course you should still be able to see it in the catalog: https://knime.learnupon.com/content-details/160819416/2.
While the key concepts are the same and the topics overlap significantly between the legacy and the current course, the current certification exam was updated and is aligned with the current L2 courses. Therefore, unfortunately, we canât guarantee that the legacy course is sufficient for passing the L2 certification.
