Firebase stream and firebase setString causing crash! #266
Description
Hi folks,
On LinkNode R8 (relay board equipped with ESP 8266), I am writing an application that I need to run "setString" while firebase streaming. However, as soon as I run "setString" after firebase stream begin function, the board crashes (error shown below). The interesting part is that, sometimes it sets the values in database and it crashes afterwards and sometimes it doesn't even set the value.
I tried many different solutions offered on other relevant issues with no luck. Below is the error code, my code and settings. Any help appreciated.
Error:
