Streaming + Firebase.sendMessage about firebase-esp8266 HOT 7 CLOSED

Please post your sketch here that I will try and investigate the problem.

Here it is:

After first call Firebase.sendMessage(firebaseData, 0) I got this errors:

If two issues you open are the same can be close one?

from firebase-esp8266.

Really, I think issues are similar. You can close one of them.

UPDATE:
I determinate, if I copy all my sketch parts from many tabs in Arduino IDE to 1 big sketch tab - all working VERY GOOD. But If I split my sketck by many tabs - then I get ERRORS. Any Ideas? It is IDE BUG?

from firebase-esp8266.

Multiple .ino files may lead to problems.
Try to declare global variables in one header file (.h file on any tab).
Then include this header file at the top of main sketch but not sure it help or not.

For big project and library developt I switch to Platformio on VS Code.

Thank you for advice.

As I test your posted sketch. No error for stack.

For stream, when FCM need to send new message, it will stop the stream connection and start new http connection to different uri due to they use the same WiFi client in Firebase Data object, and the FCM response from server is a bit slower than RTDB connection. During this time stream can't be connected and after FCM message complete it work, stream will be resumed and use time to re-connected to the stream path, you may miss stream data during this as normal behavior of multi-tasking with only one WiFi client.
