Hi @Lada,

I can’t access the S3 bucket using the credential provided. I get the following warning in my KNIME console.

WARN  Amazon S3 Connector  5:2422:0:2270 The credentials provided have restricted permissions. File browsing might not work as expected.

Subsequently there is no file in the CSV reader.
Could you help me please with this one?

Best,
Bilal

Hi @nizamibilal1064 ,

Thanks for reaching out. The permissions are indeed restricted so that you can only read the files from the bucket provided in the exercise instructions. The credentials won’t allow you to change the files and not even browse outside of the bucket. So this error is expected. Simply provide the path precisely as described in the instructions and then it should work. Let us know if you still have problems!

Best,
Lada

Hi there,

It is probably a very dumb question, but I can’t access the credentials Docs file (and I don’t have access to the KBH demo account, I used my company’s for the L3 course so never needed it), where do I request that?

Thanks!

Hi @Vonwen ,

Thanks for reaching out and reporting the issue - it’s actually on our side.

  • We updated the course with the updated link to the credentials document. To see the updated version, could you please re-enroll to the course? You should see the new course version in the cataog. You will find the new link in the Hands-on Exercise - Preparation lesson.
  • For the L4-DE course, you don’t need access to the Business Hub instance.

Apologies for the inconvenience. Let us know if you have more questions.

Best,

Lada

Good morning! I restarted the course using the new version, but the credentials listed are not allowing me to progress past the first Hands-On exercise. Am I supposed to use a different set of credentials for the KNIME Hub Authenticator node?

Hi @camaalm ,

Thanks for reaching out. I just tried it out and it works for me. Could you please elaborate what exactly you tried and what exactly failed?

Sometimes the issue arises from the confusion between configuration of the component (this would be the right place to provide credentials) or of the nodes inside the component (in this exercise you don’t need to open the component).

Also please double check that you didn’t include any trailing or leading whitespaces and that no extra space was added accidentally in the middle of the password while copying it from 2 lines.

Hi all, I have a problem with the “GET Request” in Step 2. I configured the Web Service URL, connected the String Configuration, and configured the GET Request. But I get a “Read Timeout” every single time.

Hey @pfmd86
Thanks for letting us know! I can reproduce the behavior, we are looking into it.
Please bear with us, I’ll keep you posted!

Issue should be fixed. Please keep in mind that it still might take a few seconds of loading time, but the GET Request node shouldn’t run into a timeout anymore :slight_smile:
