Hi All, I've just bumped into a problem and I just can't believe my eyes. One of our systems started to send emails with undefined values where no such values should appear. So I started to investigate the email sending subflow and added a filter condition with a node.warn() to log it and also chec…

Are you using multiple context stores? If so are you looking at the correct store in the editor?

Well, I don't think so :slight_smile: How can I check if multiple context stores are used?

If it's related to the contextStorage property, then it's in a comment block so it should not play any role here.

Do you mean the contextStorage section is entirely commented out? I find that surprising but maybe it is ok. Are you looking at the file in your .node-red folder. I guess that isn't the problem anyway, I couldn't think of any other reason it might be undefined. Is the global var regularly writte…

Yepp, the complete section is commented out. I'm 100% sure that I checked the right file in the right folder. That global variable is only set once when nodered starts up and never again. I double checked it now by searching for: global.set("farmName global.set('farmName and the editor gives onl…

[image] r0ller: What you should notice is that the global variable 'farmName' has a value in the editor when checking the global context but it is undefined when it got logged by the subflow. Does anyone have any idea? This system has recently been upgraded to 1.2.9. Previously, it was running …

I also suspected that but already ruled out. Checking all the keys gives: [image]

Does that global always show undefined in the subflow, or is it intermittent? Are there any other global vars used in the subflow?

[image] r0ller: This is how it looks like in the editor: [image] And this is what I get in the syslog from node.warn(): [image] What I don't understand is there is more to that warn statement than just getting the global. Can you try node.warn(["farmName", global.get("farmName")])

Look in settings.js for the bit about context.
