Firestore payload cuts of

[loczi1]

I have printing out the payload with Serial_Printf("payload: \n%s\n\n", fbdo.payload().c_str());

On firestore I have a document and inside that several maps/arrays.
When I create a new document from the frontend I can read the whole document back through the payload.
When I modify a a fields value directly from cloud firestore the payload loads but cuts of, not printing the last few "}" and
"createTime": "2022-03-11T19:30:06.966606Z", "updateTime": "2022-03-11T19:30:06.966606Z"

All the field are visible and accessible both from the Cloud Firestore and from the frontend.
I also add the 2 logs where you can find the difference at the end.
This is probably a bug.

If you use Firebase library, you should go to the repo page and post there.

You should tell which device you use too.

If you use this library, for ESP8266 you should set this to handle large payload

fbdo.setBSSLBufferSize

and also ESP8266 and ESP32

fbdo.setResponseSize

You cannot parse incomplete JSON, it should store in buffer before parsing, the chunked or partial data cannot be parsed until it completed and valid JSON.

Firestore payload request and response are JSON data which may be too big for ESP8266 when your data becomes complex.

There is on option to focus on a field with mask parameter.

Is this lowering also the payload?

[mobizt]

Yes only the field that defined as field mask will contain in JSON payload.
