[letonghan]

Type of Change

bug fix
API not changed

Description

Fix request.client=None issue using async UT.
fastapi.TestClient.client was set to None in
link:

• fastapi v0.109.0: accessing request.client.host in a middleware throws 'NoneType' object has no attribute 'host' when I run a test with pytest fastapi/fastapi#11019
• Revert "Turn scope["client"] to None on TestClient (#2377)" encode/starlette#2525

Expected Behavior & Potential Risk

UT of test_photoai_api.py and test_askdoc_server.py will pass.

How has this PR been tested?

Local tested on SPR.

Dependency Change?

None
