Debugging in developer tools

I often face a scenario where I’m trying to figure out why something isn’t working, so I find myself using the super useful dev tools.

However, I don’t seem to get actual error messages. Is there any reason for this?

Case in point, trying to figure out why I can’t get this climate to turn on - and node red is giving me something that’s almost useful:

But dev tools, no info at all.

Of course it could be that node red is returning more info because it’s generating its own error, but I don’t think that’s the case… either way, it would be super useful if there was a bit of a description here as to what’s going on exactly.
