Problems to load data from WeatherReport.jl

[NoelAraujo]

Hello,

I'm trying to work with temperatures extracted from WeatherReport.jl and forecast next month heat wave. Check the minimal working example below

Important: the data from export_to_sqlite is exported inside on the root folder from the WeatherReport.jl and I had to copy and paste the sqlite file manually into my working directory

In my case, the sql file was on: /home/noel/.julia/packages/WeatherReport/akdwz/export

using WeatherReport
export_to_sqlite("Araraquara", start_date = "2020-01-01", end_date = "2023-12-31")

using SQLite, DataFrames, ArarForecast, TimeSeries, Dates
db_train = SQLite.DB("Araraquara_all.sqlite")
df_train = DBInterface.execute(db_train, "SELECT * FROM temperature_2m") |> DataFrame

_dates = Date.(df_train[:,"TIME"], dateformat"yyyy-mm-dd HH:MM:SS")
_data = df_train[:, "temperature_2m"]
# _data = rand(length(_dates)) # for tests
_train = (date = _dates, data = _data);
train = TimeArray(_train; timestamp = :date)

p = 30
fc = arar(train, p, Day)

I get an error message about vector and scalar types, even though I am using the correct TimeArray input.

I don't know that to think, for instance, if I change the content of _data to random numbers, everything works as expected.

Any suggestion on what am I missing?

Thank you
