PathFinder Failing on Log Statement? #34

Closed alexgandy closed 5 years ago

alexgandy commented 5 years ago

Describe the bug Any time that rockfish finds a profitable route, it dies.

To Reproduce

  1. Clone repo, follow install instructions.
  2. Duplicate and modify example configurations.

I've tried a variety of configurations: XLM -> USD -> BTC -> XLM XLM -> USD -> SLT -> XLM

Expected behavior I'm not sure, still just poking around with Rockfish.

Screenshots Output:
