Hello,

I'm trying to open a workflow I had exported from my Mac using 3.2.1. And I get this error:

See attached screenshots.

I had tried to mannually correct the xls paths, but I still get the error:

ERROR LoadWorkflowRunnable            Workflow could not be loaded. null

 

Any ideas?

Thanks!

Do you remember which community extension might cause this? (From the stacktrace it looks like a core KNIME workflow loading problem, probably related to loops.)

I thought it was:

KNIME Spotfire integration    3.2.0.v201605301230    org.knime.features.ext.spotfire.feature.group    KNIME GmbH, Konstanz, Germany

from http://update.knime.org/partner/3.1/

 

So I had deleted those nodes from my Mac running KNIME 3.2.1 and export it again.

Then I came to my Windows running 3.2.1, and still does not import.

And I have the same error.

 

Any ideas?
