Hello, I am trying to create a chart snippet using data from the controller and using that data to create a Chart snippet.
Here is what I have managed to do and I am getting this error from the console.

Failed to load resource: the server responded with a status of 500 (INTERNAL SERVER ERROR)

Controller:

@http.route ( '/btc/usd' , auth = "public" , type = "json" , methods =[ 'POST' , 'GET' ] , csrf = False ) 
def all_bitcoin_usd ( self , **kwargs ): 
    print ( 'Calling this method >>>' ) 
    # fetch_usd = http.request.env['usd.btc.exchange'].search_read([], ['name', 'date', 'amount_paid']) 
    fetch_usd = http.request.env[ 'usd.btc.exchange' ].search([]) 
    for i infetch_usd: 
        print ( 'fetch usd' , i) 
        param = {} 
        data = dict () 
        data[ 'name' ] = i.name 
        data[ 'date' ] = i.date 
        data[ 'amount_paid' ] = i.amount_paid 
        param[ 'param' ] = data 
        n = json.dumps(param) 
        print ( 'nnn' , n) 
        return Response(json.dumps(param , default =date_utils.default) , content_type = 'application/json;charset=utf -8' ,status = 200 )
