Image generation failed with error 'Allow (All ages)' not available

Despite setting up Vertex AI API with billing I am getting following error.

15:06:41.289  E  Unknown error:
com.google.firebase.ai.type.ServerException: Image generation failed with the following error: You have chosen the 'Allow (All ages)' option for Person Generation, but this option is not available to you. If you would like to generate images with people, see the safety settings documentation for more details.

Changing ImagenPersonFilterLevel.ALLOW_ALL to ImagenPersonFilterLevel.ALLOW_ADULT does work for me. However what is the right path here?

androidify/core/network/src/main/java/com/android/developers/androidify/vertexai/FirebaseAiDataSource.kt

Lines 94 to 103 in 282985c

	private fun createGenerativeImageModel(): ImagenModel {
	return Firebase.ai.imagenModel(
	remoteConfigDataSource.imageModelName(),
	safetySettings =
	ImagenSafetySettings(
	ImagenSafetyFilterLevel.BLOCK_LOW_AND_ABOVE,
	personFilterLevel = ImagenPersonFilterLevel.ALLOW_ALL,
	),
	)
	}

I managed to get it running by excluding the safetySetting altogether:

// FirebaseAiDataSource.kt
private fun createGenerativeImageModel(): ImagenModel {
    return Firebase.ai(backend = GenerativeBackend.vertexAI()).imagenModel(
        remoteConfigDataSource.imageModelName(),
    )
}

@yannickpulver Yeah! that also worked for me! Thanks for sharing!

@hossain-khan Sorry that you ran into this, and thanks for reporting!

The ImagenPersonFilterLevel.ALLOW_ALL option is only available for projects that are part of the Person and Face generation allowlist. We are updating the refdocs to make that more clear: firebase/firebase-android-sdk#6995

For Androidify, I think changing ImagenPersonFilterLevel.ALLOW_ALL to ImagenPersonFilterLevel.ALLOW_ADULT would be the most appropriate resolution.
PRs are welcome :)
