error when opening a workflow

[cartrurod]

Hello, I have a problem when opening a workflow that I have always opened with a .knwf extension for a few days, it does not allow me to open it because it generates the error:
java.lang.NoSuchMethodError: org.knime.core.node.workflow.WorkflowContext$Factory.setMountpointRoot(Ljava/io/File;)V

I have KNIME version 3.2.0
The operating system is Windows Server 2012 R2.
knime.log (1.7 MB)

Hi @cartrurod,

searching the forum there was an identical issue that got solved by updating Knime.

Update 3.3.1 problems

After updating KNIME itself to 3.3.1 (File Menu --> Update KNIME), I then updated all the nodes and plugins via the usual mechanism (Help Menu --> Install New Software --> All available sites) Alastair

Running an outdated version, for the apparent but also security reasons (see log4J CVE), of Knime is highly discouraged. This will cause you a lot of headache in the long run ass it’s easier to do many incremental and small updates vs. huge major version jumps.

Best
Mike

Hi @cartrurod and welcome to the forum.

I first thought there must have been a typo in your post, but I checked the log and 3.2 is the version you’re using. I will reiterate what Mike said above and highly encourage you to download the latest version. As you might imagine, quite a lot has changed in the past 6+ years!
