Based on the provided error code, it is recommended to substitute "[sandbox resource group name]" with the default resource group name, commencing with "learn......" (for instance learn-9e3a1a2e-23c1-4f7d-9fa3-a1b6abce2f58). This replacement should be made adjacent to the --resource-group name, as illustrated in the accompanying. screenshot below.
Note:Kindly refrain from utilizing a personalized resource group name, such as (e.g. my-group01). Instead, consider employing a resource group name that begins with learn-9e3a1a2e-23c1-4f7d-9fa3-a1b6abce2f58, as illustrated in the provided screenshot below.
