Hi! I am working on the Firebase Web App Project. I am attempting to upload the authentication code, and I keep getting a compilation error with an extensive list of errors related to the the Firebase library. I copied the code exactly as written, only changing the necessary credentials and keys.

Hi.
Which version of the ESP32 core are you using?
I just tested the code with version 3.0.4 and everything is compiling and working as expected.

Sara
