When running a sim no HTML report or finishing statement happens. Seems to hang after a while

KINDLY READ AND ACT ON THE BELOW INFORMATION BEFORE FILING YOUR ISSUE!

Please go to our Zenbot subreddit for questions, help and support:

https://www.reddit.com/r/zenbot/

If you open a GitHub issue, here is our policy:

1. It must be a bug or a feature request.
2. The form below must be filled out.

Here's why we have that policy: Zenbot developers respond to issues. We want to focus on work that benefits the whole community, e.g., fixing bugs and adding features. Support only helps individuals and rarely leads to bugfixes or useful enhancements. GitHub also notifies hundreds of people when issues are filed. We want them to see you communicating an interesting problem, rather than being redirected to Reddit.

Remove everything above before creating your issue.

System information

• Have I written custom code (as opposed to using zenbot vanilla): no

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Ubuntu 18.04

• Zenbot version (commit ref, or version): 4.1.0

• Zenbot branch: unstable

• NodeJS version:v10.22.0

• Python version (when using a python script): python -V
  Python 3.7.2

• Exact command to reproduce (include everything): ./zenbot.sh sim binance.ETH-BTC --strategy trend_ema --days 10 --period=10m

I seem to be having this issue with ANY sim though

• Did I make any changes to conf-sample.js?: only configuring the exchange api key

Describe the problem

The sim runs and just appears to halt. After a period of time it just quits. (this time I ran the same command above with no --days argument)

Source code / Error logs

I unfortunately do not know how to turn on additional logging unfortunately and there is no stack trace printed.

I ran with --debug on the end and it appears to end up in the same place with no additional logging printed.

I ran on my other computer with a different kernel and different nodejs version and received the following error.

@DeviaVir not sure why all my specs are above. But when i replace sim.js with the following version of sim.js it seems to work all the way through.

I have a similar problem but I have no output and the process exits after a while...

@Wheaties466 changing the node version to lts/erbium worked for me. The simulation no longer hangs. I used nvm to install node so I just needed to execute 'nvm install lts/erbiuim' and im then at v12

[miqueet]

Thanks for the info I’ll try that out

Same problem on windows with node 12. I tried with docker and without using it. Di you solved? @Wheaties466

[miqueet]

I could only get it to work using the old code I linked above.

Same fix worked for me here too: #2412

EDIT: It's not really "fixed" - something is still broken, sim runs will "hang" for 30/60/90/longer at the end, doing.. Something?? And quite a few runs in the backtester just fail.

It's still borked. Hope it gets fixed soon.
