Getting WARN CEFNodeView in my first node extension

Hi everyone,
I am trying to build my first node using python but I am encountering some strange behaviours following the tutorial instructions. Once I create my first node and open its the configuration dialog I get these warning:

WARN CEFNodeView unknown format “int32” ignored in schema at path “#/properties/model/properties/some_param” (source: http://org.knime.core.ui.dialog/dialog_org.knime.python3.nodes.extension.ExtensionNodeSetFactory$DynamicExtensionNodeFactory/NodeDialog.umd.min.js; line: 1)

WARN CEFNodeView unknown format “double” ignored in schema at path “#/properties/model/properties/double_param” (source: http://org.knime.core.ui.dialog/dialog_org.knime.python3.nodes.extension.ExtensionNodeSetFactory$DynamicExtensionNodeFactory/NodeDialog.umd.min.js; line: 1)

WARN CEFNodeView unknown format “double” ignored in schema at path “#/properties/model/properties/double_param” (source: http://org.knime.core.ui.dialog/dialog_org.knime.python3.nodes.extension.ExtensionNodeSetFactory$DynamicExtensionNodeFactory/NodeDialog.umd.min.js; line: 1).

I still get the correct output from the node, I just want to understand how to solve this unknown format problem. In the picture below you can see the code provided by the beginning tutorial, it is unmodified except for knext.PythonNode in class TemplateNode. The problem seems to be in some_param and double_param.

Thank you in advance.

Hi @Fonzo454,

thanks for reporting! Please ignore this warning, it is known to us and we are working on a fix.

Best regards

Thank you very much for your reply!

I spent a whole day trying to fix it. I’ll just just keep forward then :+1:

Sorry to hear that. I hope you can continue developing nodes now :slight_smile:
