Invalid type error on every message

[morigs]

With simplest example using CodeAgent I'm getting the following error on every agent message:

Invalid type ChatMessage for attribute 'output.value' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types

model_id = environ.get("MODEL_ID", "meta-llama/Llama-3.3-70B-Instruct")
model = HfApiModel(model_id=model_id, timeout=60)

if __name__ == "__main__":
    agent = CodeAgent(
        tools=[],
        model=model
    )
    agent.run(input("ASK:"))

Try to reinstall smolagents because your code is working :

My bad, I've completely omitted the imports but the important line was there... I was importing telemetry file which does the following:

from opentelemetry.sdk.trace import TracerProvider
from os import environ
from openinference.instrumentation.smolagents import SmolagentsInstrumentor
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.trace.export import SimpleSpanProcessor

endpoint = environ.get("OTLP_SPAN_EXPORTER_ENDPOINT", "http://127.0.0.1:6006/v1/traces")
trace_provider = TracerProvider()
trace_provider.add_span_processor(SimpleSpanProcessor(OTLPSpanExporter(endpoint)))
SmolagentsInstrumentor().instrument(tracer_provider=trace_provider)

I can confirm that the message stops appearing after disabling tracing.
