JSON to Table KNIME 3.6 error

Hey there!

Since upgrading to 3.6 one of my workflows is running into an error on a JSON to Table node:
Execute failed: Found empty property at index …

JSON_to_Table_error.knwf (8.0 KB)

After some investigation I found out it happens when a property of the JSON contains a comma. Is there a specific reason for this new behaviour? Will I need to adjust my workflow for this or is a bug that will be fixed?


Thanks for the hint! At a first glance it looks like a bug, as a valid JSON key name can contain commas. We’ll investigate on this and let you know as soon as possible how we concluded. Avoiding commas in JSON keys might be the easiest workaround for you at the moment. Sorry for the inconveniences.
