[Bug]: Cannot send trace with FastAPI #804
Description
Problem Description
With FastAPI app, traces will not be sent
Root cause: The I/F of FastAPI middleware are not covered perfectly and failed to insert instana asgi middleware. For example, the following configuration avoid asgi middleware insert because tuple is not covered. (Tuple is valid as arg because FastAPI accepts Sequence as middleware)
app = FastAPI(
title="Title",
summary="Summary",
middleware=(),
)I'll make a pr to fix this
Minimal, Complete, Verifiable, Example
app = FastAPI(
title="Title",
summary="Summary",
middleware=(),
)Python Version
