Retry failing nodes with wait (Try/Catch + loop) in KNIME 5.2.5

Hi everyone,

I’m using KNIME 5.2.5 and have a workflow that intermittently fails in two nodes:

*

Create DB Table (DB SQL Executor / Hive)

*

Call Workflow Service (custom step: SSH2GBucket)

I’d like to implement a retry mechanism:

*

Retry the failing node up to 10 times

*

Wait 5 minutes between retries

*

Continue as soon as the node succeeds

*

Fail the workflow only after all 10 attempts fail

I tried using Try (Variable Ports) / Catch Errors (Variable Ports) with a Wait… node, but I couldn’t figure out how to:

*

Loop back to retry

*

Count attempts

*

Exit early on success

What’s the recommended pattern in KNIME for this?

Should this be done with a Variable Condition Loop + Try/Catch, or is there a cleaner/best‑practice approach?

Any guidance or example workflows would be really appreciated. Thanks!
