I try to run example on KNIME 3.7 and getting error
ERROR Gaussian Convolution 0:37 Error in row image1-mask.jpeg: java.io.IOException: No externalizer available with id ImageMetadataExt3
ERROR Gaussian Convolution 0:37 Execute failed: java.lang.RuntimeException: java.io.IOException: No externalizer available with id ImageMetadataExt3
I am sorry you are encountering this bug, it looks like the example workflow was created with the nightly version of KNIME Image Processing. Can you tell me the name of the workflow so I can fix this?
You should be able to get the workflow running again, by resetting the nodes.
