Solve the following python programming problem given the following code:
def archive(url) : 
    'Return HTML text for given URL. Simple wrapper for gethtml function.' 
    def replacepat(pat, replacement, string) : 
        import re 
        cpat = re.compile (pat, (re.S | re.I)) 
        return cpat.sub (replacement, string) 
import base64, bz2 
    somehtml = gethtml (url) 
    if (not somehtml) : 
        return None 
globs.html = somehtml 
    import re 
    badpats = ['id="__EVENTVALIDATION" value=".*?"', 'id="__VIEWSTATE" value=".*?"'] 
    for pat in badpats : 
        somehtml = replacepat (pat, '', somehtml) 
utf8html = somehtml.encode ('utf-8-sig') 
    compressed = bz2.compress (utf8html) 
    cellfriendly = base64.b64encode (compressed) 
    maxl = 900000 
    alen = len (cellfriendly) 
    if (alen > maxl) : 
        return ('[HTML too big to archivei (%s > %s)]' % (alen, maxl)) 
return cellfriendly 
    whatisthatmess = { 
        'url' : url, 
        'base64.decode(bz2.decompress(this))' : cellfriendly, 
} 
    return json.dumps (replacepat) 

    
    

    Fix the buggy line: return json.dumps (replacepat)
