UID is changed after token refresh

[sNapppppp]

Hi,

I'm new to this and this might be a stupid question. So, I'm using Email/Password for authentication. In the first hour my code is working perfectly, until there is this message on serial monitor:

Token info: type = id token, status = on refreshing
Token info: type = id token, status = ready

Anything after that will give me an error message: Permission denied.

I tried to see what is inside auth.token.uid variable by print it to serial monitor, turns out it was changed from 3AqbIKT8nXYzXYKfOLGZGhhS9dG2 to 3600 after token refreshed.

Here is my Firebase RTDB rules:

{
  "rules": {
    "UsersData": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null && auth.uid == $uid"
      }
    }
  }
}

Now I understand that I get Permission denied because of uid was changed, but I don't understand why it become 3600? Can anyone help me, please?

On readme I also found that authentication using email and password is not require token generation and time setup, but how to disable token generation?

Here is my firebase setup code:

  config.api_key = API_KEY;
  auth.user.email = USER_EMAIL;
  auth.user.password = USER_PASSWORD;
  config.database_url = DATABASE_URL;
  Firebase.reconnectWiFi(true);
  fbdo.setResponseSize(4096);
  config.token_status_callback = tokenStatusCallback;
  config.max_token_generation_retry = 5;
  Firebase.begin(&config, &auth);

and this is the loop:

    if (millis() - dataMillis > 60000 && Firebase.ready()) {
        dataMillis = millis();
        String path = "/UsersData/"; 
        path += auth.token.uid.c_str(); //<- user uid of current user that sign in with Email/Password

        String distancePath = path + "/Distance/" + String(epochTime);
        Serial.printf("Upload distance: %s\n", Firebase.RTDB.setInt(&fbdo, distancePath.c_str(), distance) ? "Success!" : fbdo.errorReason().c_str());

        String tempPath = path + "/Temperature/" + String(epochTime);
        Serial.printf("Upload temperature: %s\n", Firebase.RTDB.setFloat(&fbdo, tempPath.c_str(), temp) ? "Success!" : fbdo.errorReason().c_str());
    }

Update the library first.

I have the latest library installed (v2.7.0), but the issue persist.

Too little information.

Post you complete code without third party library and keep it clean and minimum here.

And post the Serial printing message too.

[mobizt]

In the code before calling Firebase.begin add this line.

config.signer.preRefreshSeconds = 3600 - 60;

This will make token expired early time in 60 seconds.

OK I have found the bugs now and create the issue here #202

I will fix this and inform you the update here.

[mobizt]

Now the issue was fixed in v2.7.1.

Please update the library.

This is now working great. Thank you!
