Which strategy? Configuration?

Same problem. Using DEMA strategy with default parameters, 1 minute candle size and 1 minute warmup period.

These look like browser console logs. Is anything else broke on the page? And do you know what button / page triggered triggered them?

This happened to me last night after pulling in the latest stable changes. I noticed that my config file was using the old syntax (paper trader variables were different) which triggered this same error. If you start from the latest sample-config.json, this might go away.

@markanderson yes this is definitely a problem (people have to make sure the config is up to date). Though I doubt this is the same as OP, since I think those are logs from the UI (which builds a config dynamically and does not use a config.js file.

Closing this as unable to reproduce, if anyone has more information on this let me know :)
