From 974db379e53e2023d60391a59baf2c110b381d49 Mon Sep 17 00:00:00 2001 From: Gal Kleinman Date: Thu, 14 Aug 2025 21:15:21 +0300 Subject: [PATCH 1/3] fix(anthropic): prevent response object corruption in beta API instrumentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fixes an issue where the Anthropic beta API instrumentation was causing LangGraph agents using Claude on Bedrock to get stuck. The root cause was that the instrumentation was directly accessing response.__dict__ which could corrupt the response object's internal state for certain object types like Pydantic models or proxy objects used by LangGraph. The fix ensures that response data extraction creates safe copies of object attributes rather than modifying or directly accessing the original response objects. This preserves the response object's integrity while still allowing the instrumentation to collect necessary metrics and token usage data. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../instrumentation/anthropic/__init__.py | 28 +- .../instrumentation/anthropic/span_utils.py | 279 +++++++++++++----- .../instrumentation/anthropic/utils.py | 127 +++++++- .../tests/test_bedrock_with_raw_response.py | 6 +- .../tests/test_beta_api_interference.py | 154 ++++++++++ 5 files changed, 490 insertions(+), 104 deletions(-) create mode 100644 packages/opentelemetry-instrumentation-anthropic/tests/test_beta_api_interference.py diff --git a/packages/opentelemetry-instrumentation-anthropic/opentelemetry/instrumentation/anthropic/__init__.py b/packages/opentelemetry-instrumentation-anthropic/opentelemetry/instrumentation/anthropic/__init__.py index 88140f2fc6..1f64a87c25 100644 --- a/packages/opentelemetry-instrumentation-anthropic/opentelemetry/instrumentation/anthropic/__init__.py +++ b/packages/opentelemetry-instrumentation-anthropic/opentelemetry/instrumentation/anthropic/__init__.py @@ -94,13 +94,13 @@ # "method": "stream", # "span_name": "anthropic.chat", # }, -
