Sorry folks, but I'm stuck what to do. Problem: A subflow gives an error and I can't search for which subflow made the error. [Screenshot from 2022-02-05 18-16-17] It's a given that an error will happen as the code in the subflow ONLY creates errors. But what you see in the debug window (right…

[image] UnborN: ok .. and this Function is in a Subflow and you have 70 instances of the same Subflow ? In THIS example: yes. (Where I created the error to demonstrate the problem) In Reality: I don't know what node is causing the problem. Other than it is from one of many subflows. I'm…

Its an interesting problem .. there is an alternative that i just tested .. do the opposite .. DONT use Catch nodes and let it throw an error! and hover over the Error msg (or double click it) and that will indicate what Subflow created it .. and once you know what msg and subflow threw it .. do…

I will probably have to do that for now. Considering I know SFA about javascript and the like.....

same here .. learning too .. much from your posts If you going the Javascript path then look into using a try catch code block lets say you have a Function and all you know is that it "may throw an error" (jk) at some point add its logic into a try catch block and handle the error the way you wan…

I had a quick look at your code, but.... I fear we are not on the same page, sorry. Your example is a given node that will error in a subflow. I don't know which node will fail in my subflows. All information sent to the catch node is processed by my code and there is nothing to point to the off…

[image] Trying_to_learn: So to catch this "one off on reboot" I have to populate my flow with ..... 70 or so catch nodes You presumably already know which flow tab it is on, from which Catch node it is. Do you have 70 subflows on one flow tab?

[image] Trying_to_learn: I don't know which node will fail in my subflows. ok .. back to the drawing board Give all your functions or nodes unique names. Use a Catch node inside the Subflow wired to output 2 [image] The bottom output will be used for error reporting which will help ident…

No, but I would say the entire flow would have 70 subflows in/on it.

[image] Colin: Do you have 70 subflows on one flow tab? I was answering that question posed by you.

That is irrelevant. If you already have a catch node on each tab then you know which tab it is.
