@mastra/langfuse tags are not working

AgentClient SDK

Hi there!
I am trying to add tags to my langfuse traces, but for some reason, it doesn't work. I am using mastra v1 and @mastra/langfuse v1.

I use it like:

export const testAgent = new Agent({
    id: 'test-agent',
    name: 'Test Agent',
    defaultOptions: {
        tracingOptions: {
            tags: ['test-tag'],
        },
    },
    instructions,
        ...
});

export const testAgent = new Agent({
    id: 'test-agent',
    name: 'Test Agent',
    defaultOptions: {
        tracingOptions: {
            tags: ['test-tag'],
        },
    },
    instructions,
        ...
});

While the trace is sent to langfuse, the tag is missing.

I also tried setting it in the calling side like:

.generate(messages, {
  tracingOptions: {
    tags: ['test-tag']
  }  
})

.generate(messages, {
  tracingOptions: {
    tags: ['test-tag']
  }  
})

but unfortunately, it also doesn't work.

Is there anything I am doing wrong or I need to know to make it work?
