According to: https://video2.skills-academy.com/en-us/azure/templates/microsoft.iotcentral/iotapps#AppSkuInfo, the SKU can be "- F1, S1, ST0, ST1, ST2".
However, I'm getting Bad Request for using S1:
{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.","details":[{"code":"BadRequest","message":"{\r\n \"error\": {\r\n \"code\": \"400.200.006.026\",\r\n \"message\": \"The sku S1 is invalid, allowed skus are ST1, ST2\"\r\n }\r\n}"}]}
please also see the attachment for the error. Please indicate which one is the source of truth. Thank you,
