IndexError: list index out of range

[dev-x0]

Expected Behavior

I assume config just moves onto next step.

Actual Behavior

Config outputs an error.

Steps to Reproduce the Problem

1. dexbot-cli configure
2. configure up to point where cli asks for external price source
3. pick any price source eg. binance and select Ok, an error will appear and the config menu will close saying IndexError: list index out of range

Specifications

• Version: 0.9.5
• OS: Ubuntu 18.04

This is related to external feeds, i will take a look after project administrative tasks

I find this bug to be introduced during @joelvai 's refactoring in december where the "none" option is commented out.

a7015ed#diff-6a2e0d37f88f35d4bcc3e1d9da39a4b4

suggest default value to be none in config element instead of exchanges[0] . will continue to look at this tmr.

[PermieBTS]

Is there a planned fix for this bug?

[bitphage]

Ok, I'm able to reproduce the problem only by using a input value outside of proposed:

External price source - The bot will try to get price information from this source

 1) Coingecko
 2) Waves DEX
 3) Kraken
 4) Bitfinex
 5) Gdax
 6) Binance

[thehapax]

I already made the fix on my branch here, the bug i did not find on whiptail but in the config elements. Here is the pull request: #503

Why are we making the assignment of this redundant? @PermieBTS @vvk

[bitphage]

@PermieBTS asked me to look into this bug.

[PermieBTS]

There was some confusion between octo and I over reassigning this issue to vvk.
My apologies
