I am facing an issue in Google Cloud's Dataprep (Perform Foundational Data, ML, and AI Tasks in Google Cloud: Challenge Lab)

Question

I am doing the challenge lab titled "Perform Foundational Data, ML, and AI Tasks in Google Cloud: Challenge Lab". However, in task 3 ("Task 3: Run a simple Dataprep job"), I am encountering an issue that is preventing me from completing the course.

I have searched online sources to see if someone has already solved the problem, but I haven't found anything. I watched videos of people completing this lab on YouTube one month ago. I believe that there may have been some changes to Dataprep, Google Cloud, or the lab settings in this one month that are now resulting in this error. I followed the same steps as the person in the video.

I am attaching the image and error logs below. The error is in the execution of the workload with the "Data flow - Run job on Dataflow" configuration. When I try to reproduce it through the "Trifacta Photon - Run job on Trifacta Photon (best for small and medium-sized jobs, up to approximately 1 GB of data)" option, I am able to execute it without any errors. However, the Qwik Labs test does not validate this configuration.

Screenshot 1 showing the problem.

Screenshot 2 showing the problem.

Screenshot 3 showing the problem.

Dataflow job execution failed: S01:PTableStoreTransformGCS3/TextIO.Write/WriteFiles/GatherTempFileResults/Reify.ReifyViewInGlobalWindow/Create.Values/Read(CreateSource)/Impulse+PTableStoreTransformGCS3/TextIO.Write/WriteFiles/GatherTempFileResults/Reify.ReifyViewInGlobalWindow/Create.Values/Read(CreateSource)/ParDo(OutputSingleSource)/ParMultiDo(OutputSingleSource)+PTableStoreTransformGCS3-TextIO-Write-WriteFiles-GatherTempFileResults-Reify-ReifyViewInGlobalWindow3/PairWithRestriction+PTableStoreTransformGCS3-TextIO-Write-WriteFiles-GatherTempFileResults-Reify-ReifyViewInGlobalWindow3/SplitWithSizing failed., The job failed because a work item has failed 4 times. Look in previous log entries for the cause of each one of the 4 failures. If the logs only contain generic timeout errors related to accessing external resources, such as MongoDB, verify that the worker service account has permission to access the resource's subnetwork. For more information, see https://cloud.google.com/dataflow/docs/guides/common-errors. The work item was attempted on these workers: Open logs

The issue is only with "Task 3"; I am able to complete the other tasks without any problems.

I have searched in many places and have not found any solution. I have seen videos from one month ago on YouTube where this issue did not appear. I believe that some changes or updates may have been made that have affected this Google Cloud lab.

Answer 1

I'm facing the exact same issue. Talked to two people from Google support and none of them could help.

Below are some default actions that they recommended to take to see if it works...

• Use your personal WiFi network and device.
• Clear cookies and caches of your browser.
• Log out from all the accounts before performing the lab.
• Open incognito mode and sign in with those credentials from which you want to perform the lab.
• Do not change accounts while performing the lab.
• Follow the instructions which are provided in the lab.
• Do not use VPN or any proxy servers.
• Use Chrome for the best response.

Also they stated that there is no ongoing issue present in the lab and many users are able to complete the lab with a 100% assessment score.

Update 04/08/2023:

The lab is back online as of now. It looks like they have addressed the issue for Task 3.
