Execute failed for Get Request Node

KNIME Analytics Platform

Hello all,

When I try to get request, I get an error as “Execute failed: org/apache/commons/io/input/BOMInputStream”…

What can be root cause of this issue? Thanks…

What sort of blue connection port is “going in” to the Get Request node?

In the log I see some Oauth2 errors… can you try get request without anything connected to it?

Hi Martin,

Yes, it comes from OAuth2, but console errors were past errors.
As you see in the picture, credentials and oauth2 executes are already successful.

Hi @erenuyanik!

Can you share the relevant part of your KNIME Log? There should be more details (especially stack traces) for the errors you’re seeing. Thanks in advance!

Does it also not work if you disconnect from oauth? In your example it does not seem to work to get to google.com - so just trying to isolate the issue.

If you need to exactly understand the errors you are seeing then I think only @leo_woerteler can help with that.

Hi Leo,

I found some detail logs when I try to execute get-request node.

Thanks for looking into it! Unfortunately that’s the stack trace of an unrelated (and benign) error. Here’s how you can get the org/apache/commons/io/input/BOMInputStream error details:

  1. Run the node again to trigger the error
  2. Open the KNIME log via “View” → “Open KNIME log”

  3. Scroll all the way to the bottom
  4. Find the log lines related to the error (containing org/apache/commons/io/input/BOMInputStream) and copy them into a reply here

I’m suspecting that it will be a NoClassDefFoundError, triggered by an inconsistent state of an extension after an update. The full error stack trace will hopefully point us to the offending extension.

Thanks again!
