Hi @carstenhaubold,
circling back to this issue as it appeared again but in a different context using a Phyton Script node while trying to extract the meta data form an image. Not even saving is possible:
I had to reset the failing node to save the workflow. Upon trying to replicate the save issue as well as the error thrown in the Python node, they were not triggered again but instead this one:
❌ KeyError: 'Sample Images'
Traceback (most recent call last):
File "<string>", line 26, in <module>
File "C:\Program Files\knime_5.2.0\bundling\envs\org_knime_pythonscripting\Lib\site-packages\pandas\core\frame.py", line 3761, in __getitem__
indexer = self.columns.get_loc(key)
^^^^^^^^^^^^^^^^^^^^^^^^^
File "C:\Program Files\knime_5.2.0\bundling\envs\org_knime_pythonscripting\Lib\site-packages\pandas\core\indexes\base.py", line 3655, in get_loc
raise KeyError(key) from err
Here is the test workflow:
Best
