Solve the following python programming problem given the following code:
def claim_name(self, name, sd_hash, amount, description = None, key_fee = None, key_fee_address = None, thumbnail = None, content_license = None, author = None, sources = None) : 
    value = { 
        'sources' : { 
            'lbry_sd_hash' : sd_hash, 
}, 
} 
    if (description is not None) : 
        value ['description'] = description 
if ((key_fee is not None) and (key_fee_address is not None)) : 
        value ['fee'] = { 
            'type' : 'LBC', 
            'amount' : key_fee, 
            'address' : key_fee_address, 
} 
if (thumbnail is not None) : 
        value ['thumbnail'] = thumbnail 
if (content_license is not None) : 
        value ['content_license'] = content_license 
if (author is not None) : 
        value ['author'] = author 
if isinstance (sources, dict) : 
        sources ['lbry_sd_hash'] = sd_hash 
        value ['sources'] = sources 
d = self._send_name_claim (amount, json.dumps (value), amount) 
    def _save_metadata(txid) : 
        d = self._save_name_metadata (name, sd_hash, txid) 
        d.addCallback ((lambda _ : txid)) 
        return d 
d.addCallback (_save_metadata) 
    return d 

    
    

    Fix the buggy line: d = self._send_name_claim (amount, json.dumps (value), amount)

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

d = self._send_name_claim (name, json.dumps (value), amount)
