AttributeError: 'ChatMessage' object has no attribute 'to_openai_format'

Deprecated to_openai_format() is causing issues with tracer.py.
Need to update tracer.py from deprecated function to the new function

Deprecated function:
m.to_openai_format()

Update to:
from haystack.components.generators.openai_utils import _convert_message_to_openai_format
_convert_message_to_openai_format(m)

Hello @JunK4i could you please check which version of the langfuse-haystack integration you are using?

We removed the usage of the deprecated ChatMessage.to_openai_format int he following PR a month ago: deepset-ai/haystack-core-integrations#1001 and since then released two new versions of the langfuse-haystack package https://pypi.org/project/langfuse-haystack/#history

Alright thanks!
