Hi,

I want to see, what's coming from outside to my SNS service in localstack like payload.
Where can I see it? I have set `DEBUG=1` but I still not see anything.
attributes = {}
    x = 1
    while True:
        name = req_data.get('MessageAttributes.entry.' + str(x) + '.Name', [None])[0]
        if name is not None:
            attribute = {
                'Type': req_data.get('MessageAttributes.entry.' + str(x) + '.Value.DataType', [None])[0]
            }
            string_value = req_data.get('MessageAttributes.entry.' + str(x) + '.Value.StringValue', [None])[0]
            binary_value = req_data.get('MessageAttributes.entry.' + str(x) + '.Value.BinaryValue', [None])[0]
            if string_value is not None:
                attribute['Value'] = string_value
            elif binary_value is not None:
                attribute['Value'] = binary_value
            if attribute['Type'] == 'Number':
                attribute['Value'] = float(attribute['Value'])
            attributes[name] = attribute
            x += 1
        else:
            break
    return attributes
def get_subscribe_attributes(req_data):
    attributes = {}
    for key in req_data.keys():
        if '.key' in key:
            attributes[req_data[key][0]] = req_data[key.replace('key', 'value')][0]
    return attributes
def is_number(x):
