Is there any way to see the current state or even any way in general to debug?
For example, I want to see the value of {{$node[“nodeName”]}} during execution.
Maybe there are some convenient breakpoints if I run it through a debugger?
yeah you can see node data during/after execution - click on any node and check the output tabs to see what data passed through it. for live debugging the easiest thing is to add a “Stop and Error” node or just a regular stop node where you want to check values, then inspect the execution data up to that point.
if you need to see specific expression values like `{{$node[“nodeName”]}}`, stick them in a Set node or Code node with console.log and check the execution logs. the expression editor also has a test feature where you can preview values before running the workflow
lmk if you need more specific debugging tips
