Falcon - Difference in stream type between unittests and actual API on post - falconframework

Question

I'm trying to write unittests for my falcon api, and I encountered a really weird issue when I tried reading the body I added to the unittests.
This is my unittest:
class TestDetectionApi(DetectionApiSetUp):
def test_valid_detection(self):
headers = {"Content-Type": "application/x-www-form-urlencoded"}
body = {'test': 'test'}
detection_result = self.simulate_post('/environments/e6ce2a50-f68f-4a7a-8562-ca50822b805d/detectionEvaluations',
body=urlencode(body), headers=headers)
self.assertEqual(detection_result.json, None)
and this is the part in my API that reads the body:
def _get_request_body(request: falcon.Request) -> dict:
request_stream = request.stream.read()
request_body = json.loads(request_stream)
validate(request_body, REQUEST_VALIDATION_SCHEMA)
return request_body
Now for the weird part, my function for reading the body is working without any issue when I run the API, but when I run the unittests the stream type seems to be different which affect the reading of it.
The stream type when running the API is gunicorn.http.body.Body and using unittests: wsgiref.validate.InputWrapper.
So when reading the body from the api all I need to do it request.stream.read() but when using the unittests I need to do request.stream.input.read() which is pretty annoying since I need to change my original code to work with both cases and I don't want to do it.
Is there a way to fix this issue? Thanks!!

It seems like issue was with how I read it. instead of using stream I used bounded_stream which seemed to work, also I removed the headers and just decoded my body.
my unittest:
class TestDetectionApi(DetectionApiSetUp):
def test_valid_detection(self):
body = '''{'test': 'test'}'''
detection_result = self.simulate_post('/environments/e6ce2a50-f68f-4a7a-8562-ca50822b805d/detectionEvaluations',
body=body.encode(), headers=headers)
self.assertEqual(detection_result.json, None)
how I read it:
def _get_request_body(request: falcon.Request) -> dict:
request_stream = request.bounded_stream.read()
request_body = json.loads(request_stream)
validate(request_body, REQUEST_VALIDATION_SCHEMA)
return request_body
