Hi, is anyone how to solve it?
First picture, I put <FirebaseESP32.h> first and then <Firebase_ESP_Client.h>.
Second picture, I put <Firebase_ESP_Client.h> first and then <FirebaseESP32.h>.
The different arrange will show different error message. Both libraries are needed, cannot remove either one. Can anyone help me? TQ
Probably only if you post the code properly, using code tags (this button in the forum editor window </> )

They are two separate libraries. You CAN'T use them both in the same sketch. Pick one and modify the rest of the sketch to work with it.
But both libraries are needed. I have no idea while modify the sketch. Are there any libraries that consists of "getString" and "Storage"? Or can I combine both libraries?
