Hi,
Had an issue with google drive file download. It was complaining about credentials. I found this very odd, and suggestions online brought me to using the HTTP node to manually make the request in the hope it would work then. And then I get an actual error saying the file is too big. That is something I can actually believe (as it is a big file)
It seems n8n doesn’t show the full error in the output. Would be nice to get this added. Would have saved me some time. 
I am assuming this is going to be applicable to all/most nodes. As it is using a helper function to generate the Error.
And I have seen it before, but normally if I am dealing with unknown errors, I have it in postman/http nodes anyways so don’t come across it to often.
Error in google drive node:
Error in HTTP request node:
I think it would be beneficial to add this because:
Save time figuring out what the actual error is.
Are you willing to work on this?
Sure if I have the time and get pointed in the right direction.
