EnvVar GOOGLE_APPLICATION_CREDENTIALS containing encoded JSON-object doesn't working in version 7.0

[mario-van-zadel]

Describe the bug

Since version 6, it seems to be possible to pass the service account via GOOGLE_APPLICATION_CREDENTIALS env variable as an encoded JSON object:

https://github.com/kreait/firebase-php/blob/6.x/src/Firebase/Factory.php#L512

After upgrading to version 7.0, the service account isn't loaded anymore and causes an Unable to determine the Firebase Project ID exception.

The Upgrade 7.0 guide doesn't mention the removed possibility to pass the service account as a string-encoded JSON object.

Is it correct that this feature has been removed or has it been removed by accident?

Uh, that has been an accident, thank you for discovering it! I just confirmed the missing capability by adding a failing test and will work on a fix right away! 💪🏻

[jeromegamez]
