Solve the following python programming problem given the following code:
def _start_method_helper(self, admin) : 
    from gcloud._testing import _Monkey 
    from gcloud.bigtable._testing import _FakeStub 
    from gcloud.bigtable import client as MUT 
    credentials = _Credentials () 
    project = 'PROJECT' 
    client = self._makeOne (project = project, credentials = self, admin = admin) 
    stub = _FakeStub () 
    make_stub_args = [] 
    def mock_make_stub(* args) : 
        make_stub_args.append (args) 
        return stub 
with _Monkey (MUT, _make_stub = mock_make_stub) : 
        client.start () 
self.assertTrue ((client._data_stub_internal is stub)) 
    if admin : 
        self.assertTrue ((client._cluster_stub_internal is stub)) 
        self.assertTrue ((client._operations_stub_internal is stub)) 
        self.assertTrue ((client._table_stub_internal is stub)) 
        self.assertEqual (stub._entered, 4) 
        self.assertEqual (len (make_stub_args), 4) 
else : 
        self.assertTrue ((client._cluster_stub_internal is None)) 
        self.assertTrue ((client._operations_stub_internal is None)) 
        self.assertTrue ((client._table_stub_internal is None)) 
        self.assertEqual (stub._entered, 1) 
        self.assertEqual (len (make_stub_args), 1) 
self.assertEqual (stub._exited, []) 

    
    

    Fix the buggy line: client = self._makeOne (project = project, credentials = self, admin = admin)

#Here is Python program to fix the buggy line: client = self.

client = self._makeOne (project = project, credentials = credentials, admin = admin)
