500 - "Internal Server Error" #50
Comments
I have the same still trying to figure this out |
I am having the same, as well.. Any help ? |
same issue |
Just resolved #53, please refer to solution over there. The POST requests from gekkoga are not compatible with gekko's backtest api. |
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. |
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.
