Dear all, I am trying to build a timeseries forecasting model using Sagemaker Canvas but receive the following error :
Your model build failed because of an issue with the Canvas server. Failure reason: <The value of "[]" should be a list of strings.>.Contact your administrator and share the details below to resolve the issue.
The dataset only consist of time_stamp, item_id and demand. I notice that the data is a bit sparse not every SKU have rows for every month. Anybody know if this might be the cause of the error or there are other possible cause ?
There are only three columns : time_stamps, item_id which is strings, and demand which is number. All the data has been check and there are no numbers in the item_id field.
