Hello,

I am getting an error running the code in part seasonal averages and long-term trends, any idea what's going on?
Thank you so much for all your work, looking forward to your responding.

maybe there are no NaNs in your timeseries. In that case no need to remove NaNs with those lines and you can set dates_nonan = dates.
You can check this by printing sum(idx_nan), if 0 then there are no NaNs
I could improve that part so that it checks first if there are NaNs before trying to remove them
