Patch for OpenTelemetry context detach method to handle None tokens gracefully.
|
|
|
|
This patch addresses the issue where OpenTelemetry's context.detach() method raises a TypeError
|
|
when called with a None token. The error occurs in the contextvars_context.py file where it tries
|
|
to call reset() on a None token.
|
|
|
|
Related GitHub issue: https://github.com/langgenius/dify/issues/18496
|
|
|
|
Error being fixed:
|
|
```
|
|
Traceback (most recent call last):
|
|
File "opentelemetry/context/__init__.py", line 154, in detach
|
|
_RUNTIME_CONTEXT.detach(token)
|
|
File "opentelemetry/context/contextvars_context.py", line 50, in detach
|
|
self._current_context.reset(token) # type: ignore
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
TypeError: expected an instance of Token, got None
|
|
```
|
|
|
|
Instead of modifying the third-party package directly, this patch monkey-patches the
|
|
context.detach method to gracefully handle None tokens.
