Request for the service to generate text completion.

Field	Description
modelUri	string The ID of the model to be used for completion generation.
completionOptions	CompletionOptions Configuration options for completion generation.
messages[]	Message A list of messages representing the context for the completion model.
tools[]	Tool List of tools that are available for the model to invoke during the completion generation. Note: This parameter is not yet supported and will be ignored if provided.

CompletionOptions

Defines the options for completion generation.

Field	Description
stream	bool Enables streaming of partially generated text.

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
createdAt	google.protobuf.Timestamp Creation timestamp.
createdBy	string ID of the user or service account who initiated the operation.
modifiedAt	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	google.protobuf.Any Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	CompletionResponse The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.

To fix, modify the prompt and restart generation.
ALTERNATIVE_STATUS_TOOL_CALLS: Tools were invoked during the completion generation.
