Android Firebase 11.2.0 MetaData causing "StorageException, an unknown error has occured"

[mitchtabian]

I tested with 11.0.4 and it works fine. 11.2.0 up to 11.4.0 cause the error. The error is at the bottom. There is a heading labeled "Error Message"

Here are the details:

1. I'm authenticated and trying to upload an image to storage. The problem isn't the image but here it is https://firebasestorage.googleapis.com/v0/b/fir-webapp-b2c06.appspot.com/o/b7a1665.jpg?alt=media&token=a2ab1033-6528-450b-a369-2fbdbaa36201
2. The image gets to about 50% upload progress and then the onFailureListener catches a failure.
3. Using version 11.0.4 works and using 11.2.0 or anything higher doesn't
4. I check the change logs here https://firebase.google.com/support/release-notes/android and it seems there was a change made regarding meta data.
5. After reading the change log I removed the meta data object from the "putBytes" method below. I reran the app and the upload worked. If you're confused this is what I did:
   Original code:
   UploadTask uploadTask = storageReference.putBytes(mBytes, metadata);
   Changed to:
   UploadTask uploadTask = storageReference.putBytes(mBytes);

Hypothesis:

Whatever change was introduced regarding the meta data in 11.2.0 is causing an issue.

Relevant code:

My Storage reference:
StorageReference storageReference = FirebaseStorage.getInstance().getReference() .child("photos/users/" + FirebaseAuth.getInstance().getCurrentUser().getUid() + "/profile_image");
My Meta Data:
StorageMetadata metadata = new StorageMetadata.Builder() .setContentType("image/jpg") .setContentLanguage("English") .setCustomMetadata("Mitch's special meta data", "JK nothing special here") .setCustomMetadata("location", "Iceland") .build();

My UploadTask:
UploadTask uploadTask = storageReference.putBytes(mBytes, metadata);

Then OnSuccessListener and so on...

I realized I probably put this in the wrong location. Not really sure where to post I just saw someone else had an error that seemed similar a while back.

Hi Mitch,
the error is raised because the ContentLanguage must be set to a 2-letter language code defined by ISO 639-1. (E.g. "en"). These two letters must also be lowercase. So neither "English" nor "EN" are valid values. I am sorry that this is currently not documented and gives a very unhelpful error message. I will look into at least updating the documentation.

In 11.0.4 and older versions of the Android SDK, there was a bug when setting the ContentLanguage. In 11.2.0, this bug was fixed and the SDK now correctly sends the content language to the server. We didn't realize at the time that fixing the bug would also lead to the server starting to reject invalid content languages or we would have documented it.

In case someone else reads this: even though this is posted under "quickstart-unity", it is an issue with the Android Firebase Storage SDK. The restriction to ISO 639-1 language codes also exists in the Unity SDK, but there never was a change in behavior.
