JWE Block Decrypt: auth_data: couldnt set additional authenticated data

[gminky019]

When decrypting a JWS payload inside of a JWT using EC keys I am having problems.

I have run into an error that says:

``auth_data=': couldn't set additional authenticated data (OpenSSL::Cipher::CipherError)`

Im not sure on how to proceed from this error. I am calling this using:

JOSE::JWE.block_decrypt(key, token).first

The key being a JWK converted from a PEM file.
The token is the encrypted payload used by decrypting the entire JWT and then grabbing the payload and passing it in.
