Using Langchain with langfuse_tags with langfuse==3.2.3 get broken:

e.g. this code worked before with langfuse==3.2.2

config['metadata'] = {
    'langfuse_tags': ['tag-1', 'tag-2'],
}
langchain_client.invoke(input, config=config, **kwargs)

but now with langfuse==3.2.3 I don't get relevant tags in langfuse interface
