Recently I have been encountering an error when using R View nodes inside parallel loops (KNIME: v3.4.0; R: v3.4.0). The specific error I get is:
ERROR R View (Table) 9:4278:4328:4152:4156 Execute failed: R evaluation failed.: "sink();sink(type='message')
This error causes the node to fail with a red 'X'. To fix this all you need to do is manually execute the node again and it will work. The loop will continue for 1-10 iterations and then fail again with an identical error.
I am trying to generate reproducible conditions for this error, but haven't been able to do so yet. Has anyone else come across this particular error recently?
