Solve the following python programming problem given the following code:
def resolve_data_source_references(job_configs, job_exec_id, data_source_urls, cluster = None) : 
    "Resolve possible data_source references in job_configs.

    Look for any string values in the 'args', 'configs', and 'params'
    elements of job_configs which start with 'datasource://' or have
    the form of a uuid.

    For values beginning with 'datasource://', strip off the prefix
    and search for a DataSource object with a name that matches the
    value.

    For values having the form of a uuid, search for a DataSource object
    with an id that matches the value.

    If a DataSource object is found for the value, replace the value
    with the URL from the DataSource object. If any DataSource objects
    are found which reference swift paths and contain credentials, set
    credential configuration values in job_configs (use the first set
    of swift credentials found).

    If no values are resolved, return an empty list and a reference
    to job_configs.

    If any values are resolved, return a list of the referenced
    data_source objects and a copy of job_configs with all of the
    references replaced with URLs.

    (by_name, by_uuid) = may_contain_data_source_refs (job_configs) 
    if (not (by_name or by_uuid)) : 
        return ([], job_configs) 
ctx = context.ctx () 
    ds_seen = { 
        
} 
    new_configs = { 
        
} 
    def _resolve(value) : 
        kwargs = { 
            
} 
        if (by_name and isinstance (value, six.string_types) and value.startswith (DATA_SOURCE_PREFIX)) : 
            value = value [len (DATA_SOURCE_PREFIX) :] 
            kwargs ['name'] = value 
else : 
            if (by_uuid and uuidutils.is_uuid_like (value)) : 
                kwargs ['id'] = value 
if kwargs : 
            ds = conductor.data_source_get_all (ctx, ** kwargs) 
            if (len (ds) == 1) : 
                ds = ds [0]

                if (ds.id not in data_source_urls) : 
                    url = _construct_data_source_url...

    
    

    Fix the buggy line: return (ds_seen, v)
assistant
#Here is Python program to fix the buggy line: return (ds_seen, v)

return (ds_seen, new_configs)
