Getting the following error while trying to run a forecast with country holidays set for Turkey, basic codes below the error.

ApiError: status_code: 500, body: {'data': None, 'message': 'Request failed with status code 500', 'code': 'B30', 'requestID': 'VPXXBHV867', 'support': 'If you have questions or need support, please email ops@nixtla.io'}

        from nixtlats.date_features import CountryHolidays

        date_features=[CountryHolidays(['TR']), 'weekday']
        finetune_steps = 2
        horizon = 30
        timegpt_fcst_df = timegpt.forecast(df=df_chicken_fresh, h=horizon, finetune_steps=finetune_steps, date_features= date_features, time_col='Date', target_col='demand')

maybe check your data-structure:

print(df.dtypes)

WRONG - Format:

unique_id object ds object y object

y should be float64

RIGHT- Format:

unique_id object ds object y float64

I have the same issue:

timegpt_anomalies_df = timegpt.detect_anomalies(df, time_col='ds', target_col='y', freq='15T')
timegpt_anomalies_df.head()
df.info()
DatetimeIndex: 35031 entries, 2023-01-01 00:00:00 to 2023-12-31 23:45:00
Data columns (total 7 columns):

 5   ds                              35031 non-null  datetime64[ns]

returns: ApiError: status_code: 500, body: {'data': None, 'message': 'Request failed with status code 500', 'code': 'B30', 'requestID': '5433HPFBJY', 'support': 'If you have questions or need support, please email ops@nixtla.io'}

Hey @RoelofKuipers. I think this is due to the names of your features, can you try removing the square brackets? e.g. replace TRR für AT [MW] with TRR für AT (MW).

This should be fixed now. Feel free to reopen if you encounter this error again.
