Hi folks,
chiming in as I checking out a recent blog post form Knime:
It links a workflow dating back to February, 28th 2020 which bears the very same issue indicating this issue dates back years by now.
Another forum post managed to “resolve” the issue by brute force … full reinstallation of Knime:
https://forum.knime.com/t/string-to-document-node-execution-failing/48812/5
I’d be interested about a solution as well. As follows my log. It is only as detailed as follows when the whole loop of the workflow is executed. Executing until the very failing node provides little more insights.
