I have a weather process that gets http information and parses it for me. This process has and does work perfectly (for some time) getting the link for my home area (from a government weather page). So I decided to copy the function changing only the web page source to "get" data for the area where…

[image] StrongTown: Node Red locks up. I can stop NR and restart it but then I get a "port is in use" error Does your function node have outputs? Where do they go? I think we need to see at least a screen capture of your flow and an export of your function node.

Also disconnect any outputs connected to the function node, to make sure that it is not something later that is causing the problem. If it still does it, then as jbudd says, select the function node and export it here, or paste the contents of the node here.

Here are the nodes without the function node output connections. Clicking "Simcoe" works fine. When the inject of 'Watford' is clicked, the get http node should just flash requesting and then clear the node status, as occurs with "Simcoe" ... and it does but only when just a debug is connected to …

[image] You have 10 while loops in your code (some of them are even nested - yuk). My money is one of these are a runaway. A first proof would be to disconnect the highlighted wire - I suspect you will have no issue. 2nd, add some "absolute max" guards in EVERY while loop to see where it goes w…

while (x < techheaders.length) { if (forecast.indexOf(techheaders[x]) > -1) { tag1 = forecast.indexOf(techheaders[x]); tag2 = forecast.indexOf('<br/>', tag1); techdata[x] = forecast.substring(tag1, tag2); ++x; } } If the if test ever fails that will stick in …

[image] Steve-Mcl: loop1++ if (loop1 > 100) { throw new Error('loop 1 is a runaway') You guys are so SMART! Truly appreciate your experience and assistance. I'm still learning how to code js well. I know there are a lot of while loops in there (and I've had my tribulations with these…

Can you explain this code? context.global.activity_tab = "Weather: "; context.global.activity_node = "Get latest forecast"; context.global.activity = context.global.activity_tab + context.global.activity_node; This is not the recommended way to handle context variables, and in my test neither glob…

I understand your concern and agree. But these are simply to create eye candy, are of no import and exist for seconds only. I have a "Process Monitor" on my dashboard that shows what my NR app is doing at any given time. These lines are in each node and feed the PM. Here's an example: [Process Mo…

I am wondering why you are not passing the http request return through an xml node to create an object. Surely this would help in using the data returned and simplify the function node considerably. Output from xml node { "feed": { "_": "\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n", …

I think I tried that at some point a while back and had issues with it (or couldn't figure it out), but that's a good point. Perhaps I should try it again. EDIT: Nope, never tried it. Don't have an XML node and didn't know one existed. But I see I can install one via the palette manager and will …

It is the latter ... global scoped variable call "activity_tab" . It has to be global so that all tabs can fed the process monitor. There is no doubt however (as you point out) that such a variable is vulnerable.
