Undefined when opportunity found, followed by invalid Bignumber error message. #51

Getting an "undefined" issue when there is profitable arb opportunity on the flash loan bot. I have changed the loan amount, and added several router addresses for different exchanges, as well as a new token.

No error thrown for this but, I do get the following error which is mentioned in another issue:

Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.5.0)

I will look into this myself, and I thank you for any help you can offer.

My bad. The problem was because of the poor error handling of axios response. Will fix that.
