This issue has been going on for multiple KNIME versions (pre v5) and is still present now, and only seems to happen on Apple machines.
When KNIME has been running for several days, at some point the String Manipulation just stops working, returning Compiling errors.
The only solution is to save the workflow, close KNIME, reload KNIME, and then the node runs.
Hi, and thank you!
That seems to be a known issue AP-19656 that will be fixed in an upcoming release of the newer software, but has also been fixed in 5.2.6 (which just dropped in the last week or two).
