i'm trying to create an NLModel within a MessageFilterExtension handler.

The code works fine in the main app, but when I try to use it in the extension it fails to initialize. Just this doesn't even work and gets the error below.

Single line that fails.
SMS_Classifier is the class xcode generated for my model. This line works fine in the main app.

let mlModel = try SMS_Classifier(configuration: MLModelConfiguration()).model

Error
Unable to locate Asset for contextual word embedding model for local en. MLModelAsset: load failed with error Error Domain=com.apple.CoreML Code=0 "initialization of text classifier model with model data failed" UserInfo={NSLocalizedDescription=initialization of text classifier model with model data failed}

Any ideas?

Anyone have any ideas or suggestions on this? I've mostly had to give up using both BERT and ELMo based models, but static models seems to work fine.
