  from sentry_sdk.integrations.pydantic_ai import PydanticAIIntegration
  sentry_sdk.init(
      dsn="<your-dsn>",
      # Set traces_sample_rate to 1.0 to capture 100%
      # of transactions for tracing.
      traces_sample_rate=1.0,
      # Add data like inputs and responses;
      # see https://docs.sentry.io/platforms/python/data-management/data-collected/ for more info
      send_default_pii=True,
      integrations=[
          PydanticAIIntegration(),
      ],

      # of transactions for tracing.
      traces_sample_rate=1.0,

• fix(strawberry): Remove autodetection, always use sync extension (#4984) by @sentrivana

  Previously, StrawberryIntegration would try to guess whether it should install the sync or async version of itself. This auto-detection was very brittle and could lead to us auto-enabling async code in a sync context. With this change, StrawberryIntegration remains an auto-enabling integration, but it'll enable the sync version by default. If you want to enable the async version, pass the option explicitly:

  sentry_sdk.init(
      # ...
      integrations=[
          StrawberryIntegration(
              async_execution=True
          ),
      ],
  )
