Hi @Akshaya Mishra, isString and isStep are mandatory columns that needs to be in your query. both are Boolean data types so you can set them as true or false based on your data.
Hi @Akshaya Mishra! You can avoid this issue by selecting “Create or Update Time Series” instead of “Create Time Series” which is the one you selected. This is chosen in the very beginning when you create a new Transformation.
