API Seeking Help

I keep getting this error and i have no idea how to fix it . KeyError: 'longs' There was a runtime error on line 63.

Here is the code

def my_rebalance(context,data):
long_secs = context.output[context.output['longs']].index
long_weight = 0.65 / len(long_secs)
short_secs = context.output[context.output['shorts']].index
short_weight = -0.35 / len(short_secs)

it only pulls this error for the 'longs' part but not for the 'shorts' part just below it which is pretty much the same.

Zeno,

Without seeing more of the code, it's tough to help troubleshoot the problem. I would recommend either running a 'Full Backtest' and attaching it to a post/comment, or create a support ticket and grant our support team permission to take a look.

My hunch is that your pipeline doesn't have a column called 'longs', but it could be something else.
