I am looking for how to present my null values with the Azure Data Factory Dataflow activity. Currently, I am using standard dataflow for modelling my data from Azure SQL database and drag it into Blob storage in JSON format. But if the dataset source has a null value, the column in the row is skipped in JSON.
Please, give me some advice on how to proceed, in order to resolve the problem. With Copy activity I don't have the same issue - null values are presented with "".
