+#### List of moduls configuration for fallback
+SAP GEN AI Hub supports a fallback mechanism for handling errors. This mechanism allows you to specify a list of fallback modules to use in case of errors. The fallback modules should contain all parameters that are required for configuring the request.
+
+Required parameters:
+- `model` 
+- `messages`
+
+Optional parameters: 
+- `filterings`
+- `groundings`
+- `translations`
+- `masking`
+- `tools`
+
+- and any of model's specific parameters.
+
