Change the path to the file be relative to the workflow:

Part 1 - KNIME Hub

Exercise 01 Deploying a Schedule

Learning objective: In this exercise you will learn how to move a workflow to production in KNIME Hub.

Workflow description: This workflow asks you to upload a report builder workflow onto KNIME Hub, schedule an execution for it, fix a bug, version the fixed version, and then finally re-execute it.

You'll find the instructions to the exercises in the yellow annotations.

Step 1. Uploading the workflow to KNIME Hub

1. Upload the folder Part 1 to one of your spaces on KNIME Hub. Make sure to include the workflows and the data.

2. Version the workflow on KNIME Hub.

3. Schedule an execution of this workflow:

   • 2 min later, send yourself a notification on successful/unsuccessful execution,

   • In Advanced settings, select the User execution scope, and create the deployment

4. (Spoiler) The workflow will fail. Inspect the job and recognize the error.

5. It's time to fix the bug! Edit the workflow and create a new workflow version.

6. Schedule the workflow again and check the produced results. Remember to set the execution scope to User in the advanced settings!
