HTTP Post sensor

Hi and thank you in advance for your support.

I’m using HTTP Post to send state from different sensors and I have a strange behavior as some time, even if the HTTP Post succeeded (code 200), the state is not create on the db (I checked the value using sqllite web interface.

{“content-type”:“application/json”,“location”:"/api/states/sensor.CPT_EAU_INDEX",“content-length”:“358”,“date”:“Sat, 29 Aug 2020 07:21:05 GMT”,“server”:“Python/3.8 aiohttp/3.6.2”,“connection”:“close”,“x-node-red-request-node”:“b314bdb2”}

Is there a way to log what is going on using HTTP POST?
I can’t find why some requests worked and some failed?

Thanks.
