Solve the following python programming problem given the following code:
def testValetServiceBottleStreamSecure(self) : 
    '
        Test Valet WSGI service request response stream sse
        ' 
    console.terse ('{0}
'.format (self.testValetServiceBottleStreamSecure.__doc__)) 
    try : 
        import bottle 
except ImportError as ex : 
        console.terse ('Bottle not available.
') 
        return 
store = storing.Store (stamp = 0.0) 
    app = bottle.default_app () 
    @ app.get ('/stream') 
    def streamGet() : 
        '
            Create test server sent event stream that sends count events
            ' 
        timer = StoreTimer (store, duration = 2.0) 
        bottle.response.set_header ('Content-Type', 'text/event-stream') 
        bottle.response.set_header ('Cache-Control', 'no-cache') 
        (yield 'retry: 1000

') 
        i = 0 
        (yield 'id: {0}
'.format (i)) 
        i += 1 
        (yield 'data: START

') 
        n = 1 
        while (not timer.expired) : 
            (yield 'id: {0}
'.format (i)) 
            i += 1 
            (yield 'data: {0}

'.format (n)) 
            n += 1 
(yield 'data: END

') 
console.terse ('{0}
'.format ('Building Valet ...

    wireLogAlpha = wiring.WireLog (buffify = True, same = True) 
    result = wireLogAlpha.reopen () 
    serverCertCommonName = 'localhost' 
    serverKeypath = '/etc/pki/tls/certs/server_key.pem'

    self.assertIs (alpha.servant.reopen (), True) 
    self.assertEqual (alpha.servant.ha, ('0.0.0.0', 6101)) 
    self.assertEqual (alpha.servant.eha, ('127.0.0.1', 6101)) 
    console.terse ('{0}

    wireLogBeta = wiring.WireLog (buffify = True, same = True) 
    result = wireLogBeta.reopen () 
    clientKeypath =...

    
    

    Fix the buggy line: self.assertEqual (wireLogBeta.respondent.headers ['content-type'], 'text/event-stream')

#Here is Python code to fix the buggy line: self.

self.assertEqual (beta.respondent.headers ['content-type'], 'text/event-stream')
