I was developping a worklow to transform a table format to a JSON one. One of my workflow node is the ‘JSON Transformer’ and it was working well.
Today I updated Knime from 3.7.1 to 3.7.2 and I am not able anymore to configure this node.
I tried the double click with the left mouse, the right click and then select ‘Configure’ and also the F6 button but I I am not able to open the windows dialog.
Does anyone have this issue ?
For your information, I am using other JSON nodes like ‘Table to JSON’ or ‘JSON Combiner’ and I do
not have this issue.
I cannot replicate this with 3.7.2 on macOS (10.13.6) - are there any errors reported in the KNIME Console or either of the log files under your workspace’s .metadata directory?
Does it change anything if you drop a new JSON Transformer node into your workflow? If you make a new workflow from scratch? If you upgraded from within KNIME from 3.7.1 to 3.7.2, what happens if you download a fresh whole version of 3.7.2 from knime.org?
I have an error in the log file Under the .metadata directory, I paste it below.
I already tried to drop a new JSON Transformer node in my workflow or to create a workflow from scratch but I still have this issue.
I will try to download the 3.7.2 from the website.

Yes - this is a problem related to the architecture change that happened between 3.7.1 and 3.7.2 - please try a fresh download and let me know if the problem evaporates.
