Hi, thank you for support.
I have an error when using notify_plugin, on my server, I cannot receive any information of block, it only prints undefine. Here is detail
On my nodeos:

On my server: (I show code)

const express = require(‘express’);
const app = express()

const port = 8082

app.post(‘/notify’, function (req, res) {
console.log(req.body)
console.log(req) //It will be log :'undefine'

res.sendStatus(200)
});
app.listen(port, () => console.log(Example app listening on port ${port}!))

## Notify Plugin
plugin = eosio::notify_plugin
# notify-filter-on = account:action
notify-filter-on = b1:
notify-filter-on = b1:transfer
notify-filter-on = eosio:delegatebw
# http endpoint for each action seen on the chain.
notify-receive-url = http://127.0.0.1:8080/notify
# Age limit in seconds for blocks to send notifications. No age limit if set to negative.
# Used to prevent old actions from trigger HTTP request while on replay (seconds)
notify-age-limit = -1
# Retry times of sending http notification if failed.
notify-retry-times = 3

do you add above parameter to your config.ini?

[Onotoko]

Yes, here is my config.ini:

# Plugin(s) to enable, may be specified multiple times
# plugin =
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::producer_plugin
## Notify Plugin
plugin = eosio::notify_plugin
notify-filter-on = lala:creatuser
# http endpoint for each action seen on the chain.
notify-receive-url = http://127.0.0.1:8082/notify
# Age limit in seconds for blocks to send notifications. No age limit if set to negative.
# Used to prevent old actions from trigger HTTP request while on replay (seconds)
notify-age-limit = -1
# Retry times of sending http notification if failed.
notify-retry-times = 3

i see the information,

thread-1 json.cpp:460 from_string
warn 2019-03-06T04:25:03.008 thread-1 http_async_client.hpp:94 post_sync ] dest: http://127.0.0.1:8082/notify payload: {“irreversible”:true,“actions”:[{“tx_id”:“a77e5c7c28dd10d11d0cc7e5e6f50bfe211b60a14d9efebe1f8099ee3a694972",“account”:“lala”,“name”:“creatuser”,“seq_num”:0,“receiver”:“lala”,“block_time”:“2019-03-06T04:25:02.000”,“block_num”:96343,“authorization”:[{“actor”:“lalala”,“permission”:“active”}],“action_data”:{“username”:“lalala”,“user_id”:22,“user_name”:“frist”}}]} 

there will be samiler message send for you service.
`On my server: (I show code)

const express = require(‘express’);
const app = express()

const port = 8082

app.post(‘/notify’, function (req, res) {
console.log(req.body)
console.log(req) //It will be log :'undefine'

res.sendStatus(200)
});
app.listen(port, () => console.log(Example app listening on port ${port}!))`
maybe the problem is your server.
