Hello there, This error message indicates the SAS URL points to a valid bucket, however the signature does not allow Terra to perform the necessary operations to populate your bucket with health and fitness data. When generating the URL, make sure the check the appropriate permissions to allow Terra to Read, Update, Create, Add, Delete files.

You will know the URL is valid when it contains the query parameter sp=racwd which indicates all the necessary permissions have been provided.

That worked! Thank you. Why does Terra need the delete permission? Why would files ever be deleted in this case

Good question, the Delete permission is only used when setting up the destination for the first time. We write and delete a healthcheck file to the destination in order to test the connection

Got it, thank you
