Not creating/updating a field in firestore document when path is long about firebase-esp-client HOT 3 CLOSED

It's not bug.

You don't show which device you used, I guess ESP8266.

You should increase the BearSSL buffer for rx and tx, like this

fbdo.setBSSLBufferSize(2048, 1024); //2048 bytes for rx and 1024 bytes for tx.

The default rx and tx buffers are 1024 and 512 by default and may be too small for large payload.

Yes, the device is ESP8266.

Even after increasing BearSSL buffer size as suggested. Still, it's getting failed without error message.

Your document path contains spaces, which should be avoid.

The space should be encoded to %20 string.

Library doesn't do extra works for path encoding for you and you should do it yourself.
