I am not a developer but use Julia for my research as there is an existing nowcasting model.
The model works well for the US data (GDP) but comes with ERROR when I replace (manually) the US GDP dates by country of interest GDP dates.
Replacing these data in excel return error in julia as on the image below .

PS: I did even change the sheet but still the same error. It only works for the original USD GDP dates.
