Error 0057

Exception occurs when attempting to create a file or blob that already exists.

This exception occurs when you are using the Export Data module or other module to save Azure ML results to Azure blob storage, and you attempt to create a file or blob that already exists.

You will receive this error only if you previously set the property Azure blob storage write mode to Error. By design, this module raises an error if you attempt to write a dataset to a blob that already exists.

• Open the module properties and change the property Azure blob storage write mode to Overwrite.
• Alternatively, you can type the name of a different destination blob or file and be sure to specify a blob that does not already exist.
