Cannot read property 'exchange' of undefined

[CryptoCoeus]

Hey Guys,

My gekko version 0.6 & gekkoga is the latest stable version - as of date.

When i run, i am following errors :

Gekko :

uncaughtException TypeError: Cannot read property 'exchange' of undefined
    at Object.<anonymous> (/Users/CryptoCoeus/gekko-geneticAlgo/plugins/sqlite/handle.js:28:27)

gekkoga :
No previous run data, starting from scratch! Starting GA with epoch populations of 20, running 5 units at a time! { StatusCodeError: 500 - "Internal Server Error"

Does anybody have any idea what is wrong ?

Same issue! On Windows 10. Updated everything but it still does not work. I think there is something extra missing that should be installed, but i have no idea what...

Gekkoga cmd:

node run -c config/your-new.js
No previous run data, starting from scratch!

In your gekko repository (not gekkoga), find web/routes/backtest.js.

Change line 26 to var req = this.request.body.gekkoConfig || this.request.body;.

Obviously this is a makeshift solution, but it addresses the issue & shows where the changes should be made in gekkoga (the POST payload does not agree with gekko).

You will then get a timeout error after running gekkoga, unfortunately. To solve this issue, checkout pull request #49:

git fetch origin pull/49/head:49

git checkout 49

Then create your-config.js again with the sample-config.js from #49 before running gekkoga.
