Solve the following python programming problem given the following code:
def get_resources(self, name = None) : 
    res_url = url (self.catalog.service_url, ['workspaces', res_url.workspace.name, 'coveragestores', self.name, 'coverages.xml']) 
    xml = self.catalog.get_xml (res_url) 
    def cov_from_node(node) : 
        return coverage_from_index (self.catalog, self.workspace, self, node) 
if (name is not None) : 
        for node in xml.findall ('coverage') : 
            if (node.findtext ('name') == name) : 
                return cov_from_node (node) 
return None 
return [cov_from_node (node) for node in xml.findall ('coverage')] 

    
    

    Fix the buggy line: res_url = url (self.catalog.service_url, ['workspaces', res_url.workspace.name, 'coveragestores', self.name, 'coverages.xml'])
