Http request keeps requesting, kills Node-RED server

General
1

Hello, my http request keeps the status "requesting" and will eventually kill the Node-RED server on my Raspberry Pi.

So far I built two other http request flows, to get data from websites. Those are running very happily for some time now. This one is behaving differently. Why, and how to solve it?

This is the flow:

The homepage of the local waste service can be retrieved without problems. Also the page with the form to enter postal code and home number: https://inzamelschema.rmn.nl/
Entering 3704DV and 127 will lead to url https://inzamelschema.rmn.nl/adres/3704DV:127
This url won't retrieve any response. Just putting it in several browsers without visiting the website or form before will give the information straightaway.

Running v1.04 on node.js v12.16.1, Raspberry PI with Ubuntu 18.04 LTS

Any thoughts? Thanks!

Running Node-RED on my Windows laptop too, now. Flow also crashes the server.

I think what youre seeing is node getting stuck in a loop (and therefore unable to update the status of the request node from requesting)

PROOF: disconnect the "Get table" function & run it - the request operates normally.

There are a few do...while loops in your function "Get table" - this will be the cause. 100% certain!

Put MAX counter in your loops (set for say max 1000 iterations (should be enough right?)) then if you hit MAX, send a node.warn("Breaking out of do..while loop 1 as it has done 1000 iterations! check this code - its not right!"); then exit the loop (to prevent node-red locking up.

In fact, litter your code with node.warn("thisVal=" + thisVal) type calls to see whats going on.

My suspicion you're not doing the regex correctly and getting stuck in loop.

PS, you might actually be able to do most of this using the html node (no regex required)
