500 - "Internal Server Error"

[123qweas]

I get this Error sometimes and I cant figure out why. The GA works fine and suddenly I get this Error. I cant recreate it or find any reason why I get this one so randomly. The GA can run for 12 hours and suddenly I get this Error, but sometimes after 5 minutes I get this error. I tried diffrent strats and diffrent parameter, nothing helps. Maybe someone had this Error too and has a solution.

[amigoni]

I have the same still trying to figure this out

[CryptoCoeus]

I am having the same, as well..

Any help ?

[mizio85]

same issue

[matthhong]

This is the same issue as #53 except #53 is more specific.

[matthhong]

Just resolved #53, please refer to solution over there.

The POST requests from gekkoga are not compatible with gekko's backtest api.

[Stefan-Stefan1]

Solved it by deleting the result. I dont know why but when the backtest is not not finding a better solution (score: -5, profit: -5, sharpe: -5) and i run the run.js again, it will break after the first run.
