Solve the following python programming problem given the following code:
@ classmethod 
def parse_test(cls, base_url, node, input_test = None, test_path = None) : 
    ' Create or modify a test, input_test, using configuration in node, and base_url
        If no input_test is given, creates a new one

        Test_path gives path to test file, used for setting working directory in setting up input bodies

        Uses explicitly specified elements from the test input structure
        to make life *extra* fun, we need to handle list <-- > dict transformations.

        This is to say: list(dict(),dict()) or dict(key,value) -->  dict() for some elements

        Accepted structure must be a single dictionary of key-value pairs for test configuration ' 
    mytest = input_test 
    if (not mytest) : 
        mytest = Test () 
node = lowercase_keys (flatten_dictionaries (node)) 
    CONFIG_ELEMENTS = { 
        'auth_username' : [coerce_string_to_ascii], 
        'auth_password' : [coerce_string_to_ascii], 
        'method' : [coerce_http_method], 
        'delay' : [(lambda x : int (x))], 
        'group' : [coerce_to_string], 
        'name' : [coerce_to_string], 
        'expected_status' : [coerce_list_of_ints], 
        'delay' : [(lambda x : int (x))], 
        'stop_on_failure' : [safe_to_bool], 
        'body' : [ContentHandler.parse_content], 
} 
    def use_config_parser(configobject, configelement, configvalue) : 
        " Try to use parser bindings to find an option for parsing and storing config element
                :configobject: Object to store configuration
                :configelement: Configuratione element name
                :configvalue: Value to use to set configuration
                :returns: True if found match for config element, False if didn't
            " 
        myparsing = CONFIG_ELEMENTS.get (configelement) 
        if myparsing : 
            converted = myparsing [0] (configvalue) 
            setattr (configobject, configelement, converted) 
            return True 
return False 
for (configelement, configvalue) in node.items () : 
      ...

    
    

    Fix the buggy line: if isinstance (templates, dict) :
assistant
#Here is Python code to find an option for parsing and storing config element
.

if isinstance (configvalue, dict) :
