So I download the Lean package from GitHub, I compile and run it just fine without actually editing the config.json file in the launcher project. No problems there.
But as soon as I enter my user Id and password from my account page into the config.json (and also set to backtesting-desktop), I start getting exceptions on launch that halts the program. The dump of the exception is below.
The interesting thing is if I back out my config.json changes, and re-run I still get the exception. So there must be some local file changes happening when I first run with my username, and that blocks any further executions no matter what is in the config.json file.
Any Ideas?
Thanks,
Chris

I revisited this and figured it out. I had the API token and password switched into the wrong fields. When I swapped them, it worked. So if your ID and password are incorrect, you get super-cryptic exceptions that lead you down the wrong rabbit hole.
