Hi,
I have a node-red instance running on a vm with Windows 10 where the language OS is set to Italian.
The debug node is returning error in the same language ( in my case Italian ).
Is there a way to change the debug node language to english?
My "View" language is alredy set to "English"
I'm not sure of the internals here, so could be incorrect but I think the View setting is for the editor labels, and isn't setting the language for the runtime, I think that is taken from the OS.
The error is originating from the Node runtime, and it will likely be using the OS language.
I set mine to Korean, and I still get the English language in debug (but labels in the editor are Korean)
unless a restart is needed to apply it to the runtime 
As Marcus says, this is not a debug pane issue. The node generating the error is generating it, or is passing it on to you. Since that looks like a database error it may be the database driver that is providing it and nothing to do with node-red.
Try adding process.env.LANG="en-US" to the very top of your settings.js file and restart Node-RED.
Adding "process.env.LANG="en-US"" do not change nothing.
The node that gives it is PostgreSQL but the database was installed in english.
I will try to change the SO language and check if it will fix mine problem
