The nodes in my workflow suddenly stops working

Weeks ago I successfully built half of the nodes I need for my workflow. Took a week break and when I got back none of the nodes worked anymore (no one has access to my account so it wasn’t tampered with).

First, the Reddit url in the http request nodes stopped working, it stopped extracting nested Reddit comments and even posts (mind you, no reddit api or endpoints where changed between sep & nov). Then my code JavaScript nodes started hanging indefinitely even when 1 write the simplest script.

I switched to code python nodes which started working. Less than 5 mins ago, I decided to upgrade to version 1.1118.2 and just like that the python code that was working well started returning errors.

This will probably take me days to fix (since I’m not an expert yet), but I can’t keep working on the same nodes forever.

Perhaps the problem is from me, how do I fix this?
