+| `APP_KIND` | `workflowApp` | Required to set the app type for the Standard logic app resource. |
 | `AzureWebJobsStorage` | None | Sets the connection string for an Azure storage account. For more information, see [AzureWebJobsStorage](../azure-functions/functions-app-settings.md#azurewebjobsstorage) |
-| `FUNCTIONS_WORKER_RUNTIME` | `dotnet` | Sets the language worker runtime to use with your logic app resource and workflows. However, this setting is no longer necessary due to automatically enabled multi-language support. <br><br>**Note**: Previously, this setting's default value was **`node`**. Now, **`dotnet`** is the default value for all new and existing deployed Standard logic apps, even for apps that had a different different value.

 | `ServiceProviders.Sftp.FileUploadBufferTimeForTrigger` | `00:00:20` <br>(20 seconds) | Sets the buffer time to ignore files that have a last modified timestamp that's greater than the current time. This setting is useful when large file writes take a long time and avoids fetching data for a partially written file. |
 | `ServiceProviders.Sftp.OperationTimeout` | `00:02:00` <br>(2 min) | Sets the time to wait before timing out on any operation. |
 | `ServiceProviders.Sftp.ServerAliveInterval` | `00:30:00` <br>(30 min) | Sends a "keep alive" message to keep the SSH connection active if no data exchange with the server happens during the specified period. |
