Python View: CEFNodeView Error

KNIME Extensions
1

Python View nodes have stopped displaying an Output Preview within the configurator and raise this error:

ERROR CEFNodeView Uncaught (in promise) SecurityError: Sandbox access violation: Blocked a frame at "http://org.knime.core.ui.dialog" from accessing a frame at "http://org.knime.core.ui.dialog". The frame being accessed is sandboxed and lacks the "allow-same-origin" flag. (source: http://org.knime.core.ui.dialog/uiext-dialog/3_3/assets/index-6ef07e53.js; line: 879)

The Python Interactive View still works fine from the workspace, it just doesn’t load in the configurator. Does anyone know how to fix this?

Cheers!

Hi Steffen,

Thanks for looking into this. Last week I updated to version 5.2.3. Everything was working fine before I updated. I’ve attached an image of all my package version below:

Hey James,

We could identify the problem and it is a bug on our end. There is currently no workaround. We will try to fix it as soon as possible and include it in a coming 5.2.4 and 5.3.

Sorry for the inconvenience.

Greetings,
Daniel

Hi Daniel,

Thank you for your response. It’s really useful to know its a bug and not a problem on my end. Shame there’s no work around, but I look forward to a fix in the next update.
