Cloak with changeset issue - (UndefinedFunctionError) function Cloak.EncryptedBinaryField.equal?/2 is undefined or private
Hi All,
I am using Cloak 0.6.2 version. It was working all good. I upgraded the Elixir version to Elixir 1.13.0, Phoenix - 1.5.9 and phoenix_pubsub : 2.0.
After upgrading, I am getting the following error
- (exit) an exception was raised:
** (UndefinedFunctionError) function Cloak.EncryptedBinaryField.equal?/2 is undefined or private
(cloak 0.6.2) Cloak.EncryptedBinaryField.equal?(nil, “Basement Flat, 2 Barons Court Road”)
(ecto 3.7.2) lib/ecto/changeset.ex:576: Ecto.Changeset.cast_field/8
I am passing the changeset in this way
struct
|> cast(
upcase(params, [:current_address_postcode]),
~w[
current_address_street current_address_locality current_address_county
current_address_postcode current_address_udprn
]a
)
It was working all good previously, now it is throwing error.
Any help to fix this, would be highly appreciated.
Thanks,
Santosh T

That version of Cloak is too outdated to work with the current version of Ecto - the semantics of Ecto.Type changed to require that equals? function in Add use Ecto.Type · elixir-ecto/ecto@c040b7c · GitHub
This issue suggests you’ll want to upgrade to at least Cloak 1.1.0:

I don’t think you need any data migration. An encrypted value has all the details of the cipher that was used for encryption.

What is the previous and the current version? Can you share your Cloak config (skipping the encryption key, obviously)?

Sorry for giving you a confusing advice. Since you’re updating from a pretty old version of Cloak, I think you should follow the upgrade guide and perform each minor version upgrade step by step, that is upgrade 0.6 to 0.7, 0.7 to. 0.8, etc. until you migrate to the latest one.

As you can see in the guide, this indeed will require a data migration.

Like @stefanchrobot suggests, you’ll need to upgrade cloak incrementally to catch up. You’ll also need to do this before changing your Ecto etc version, as vintage cloaks are not compatible with current Ecto.
