Help: Token info: type = undefined, status = error

[cfficaurzua]

I am testing the AccessTokenFile.ino
I put the gtsr1.pem and service_account_file.json (downloaded from Project settings > Service accounts > Firebase Admin SDK > Generate new private key). in data folder inside the project.
The only thing I changed is the URL, SSID and PASSWORD?
I am missing something? what else do I have to perform.

Connecting to Wi-Fi........
Connected with IP: 192.168.100.89

Firebase Client v3.15.5

Token info: type = undefined, status = error
Token error: code: -127, message: Missing required credentials.

Thx

See the example, read all comments and edit your credential information and test it.

With your own code, you need to provide all required credentials for authentication.

If you follow this example, you need to upload the key file (service account json file) to your filesystem.

In Arduino IDE, close the Serial Monitor window (if opened), select Tools -> ESP32 Sketch Data Upload

Thanks this helped me a lot, I didn't know that.
This tool isn't installed by default. I had to install it (https://randomnerdtutorials.com/install-esp32-filesystem-uploader-arduino-ide/)

The certificate file is optional for server authorization checking.
