gRPC aio ServerInterceptor missing isolation_scope per request

[robinvd]

Description

The async gRPC server interceptor (sentry_sdk/integrations/grpc/aio/server.py) does not create an isolation_scope() per request, unlike its sync counterpart and every other request-handling integration.

This causes scope state (attachments, tags, breadcrumbs, extras) to leak between requests.

Sync vs Async

The sync interceptor correctly isolates each request:

sentry-python/sentry_sdk/integrations/grpc/server.py

Line 42 in 11d8a78

with sentry_sdk.isolation_scope():

with sentry_sdk.isolation_scope():
    ...
    with sentry_sdk.start_transaction(transaction=transaction):
        return handler.unary_unary(request, context)

The async interceptor skips isolation:

sentry-python/sentry_sdk/integrations/grpc/aio/server.py

Line 59 in 11d8a78

with sentry_sdk.start_transaction(transaction=transaction):

# no isolation_scope()
with sentry_sdk.start_transaction(transaction=transaction):
    return await handler.unary_unary(request, context)

Other async integrations all use isolation_scope():

• ASGI
• aiohttp
• Tornado

Impact

We add various debug attachments to the sentry scope. And on sync grpc this works, but on async grpc every request gets all the attachments from the previous requests to the same pod. Causing more storage usage and weird debug viewing.

Expected fix

Wrap the handler in sentry_sdk.isolation_scope(), matching the sync implementation:

async def wrapped(request, context):
    name = self._find_method_name(context)
    if not name:
        return await handler(request, context)

    with sentry_sdk.isolation_scope():
        transaction = sentry_sdk.continue_trace(...)
        with sentry_sdk.start_transaction(transaction=transaction):
            ...

i can make a 1 line PR if you agree :)
