You should provide the code and check your free memory before calling Firebase functions. Nothing can help based on your info.

is what I 'm doing,

btw indicating seems related to function:

void FirebaseESP32::delS(char *p) { if (p != nullptr) delete[] p; }

it seems to hangs when launch the delete[] p

can I ask you what's the role of this function to start debugging ?

I don't understand what you are trying to do.

Please learn the basic C or C++ programming.

The error from decoded trace is about dynamic memory allocation by calling new to allocate the memory then the delete was called to free the memory.

The error may occur when not enough memory for allocation with the desired amount due to you misused the stream.

The data at that node in the database which you're trying to stream is too large to handle by the limited memory device.

You should reduce the data to get from stream.

You should also update the ESP32 Core SDK.
