Description

yesterday my token counting call was working fine, no code changes and today I have this error.

Error at ligne final tokenCount = await VertexClientAI.instance.countTokens([
Content.functionResponse(functionCall.name, functionResult)
]);

My snippet code

  final functionCalls = response?.functionCalls.toList();
      if (functionCalls != null && functionCalls.length > 0) {
        await Future.forEach(functionCalls, (functionCall) async {
          try {
            final functionResult =
                await VertexFunctionsAI.orchestration(functionCall);
            if (functionResult != null) {
              //
              // new error here
              //
              final tokenCount = await VertexClientAI.instance.countTokens([
                Content.functionResponse(functionCall.name, functionResult)
              ]);
              //
              //
              log('Function token count: ${tokenCount.totalTokens.toString()}');
              GenerateContentResponse? responseFunction =
                  await chatSession?.sendMessage(Content.functionResponse(
                      functionCall.name, functionResult));

              responses.add(responseFunction);
              textResponse = textResponse + (responseFunction?.text ?? "");
            }
          } on VertexAIException catch (e) {
            log('Error VertexAI ${e.message}');
            return UnimplementedError('Error VertexAI ${e.message}');
          }
        });
      } else {
        textResponse = response?.text ?? "";
      }

Additional context and comments

No response

Additional information: the countTokens method works well with the count Content.multi([]) but not when using a count
Content.functionResponse()

[MichaelVerdon]

Hey there, I am unable to reproduce this issue, countTokens works fine for me in my application using the latest version, I believe the issue must lie in your implementation as your Content.functionResponse() might be missing fields or be submitting something for countTokens in the wrong format. This could explain why Content.multi([]) is working for you as it accepts multiple contents.

[russellwheatley]

Just to give further context, the exception is thrown here: https://github.com/firebase/flutterfire/blob/main/packages/firebase_vertexai/firebase_vertexai/lib/src/api.dart#L697-L709

The reason why it threw an exception is because totalTokens is missing in the JSON object. That function is parsing the response made from the VertexAI server here (parse()): https://github.com/firebase/flutterfire/blob/main/packages/firebase_vertexai/firebase_vertexai/lib/src/model.dart#L176

It seems like the server isn't returning totalTokens property.

@Lerobindesbois - it does seem odd that it isn't being returned. What version of vertexAI package are you using?

[Lerobindesbois]

@russellwheatley the version is writing in the title Issus version 1.1.1 ;-)

I've been writing this chatbot for 2 weeks and everything was working fine. The call to the method for calculating the Content.functionResponse token worked fine. And it stopped working 3 days ago.

if you look my snippet code :
calling the counTokens method passes the same parameter from Content.fucntionResponse as the parameter to chatSession.sendMessage() and it works fine for sending the message to VertexAI. And this is the only way to receive the number of tokens for a function.

In the jsonObject the call to the method for a Content.functionResponse does not return the 'totalTokens' attribute in the object.
Why?

Hey @Lerobindesbois are you still experiencing issues?
