NameError: uninitialized constant StoreModel::Types::ArrayType

[alkesh26]

We recently upgraded our application from Rails 5.2.8 to the 6.1.7 version. We are using the 3.1.2 Ruby version and the 1.2.0 version of the StoreModel gem.

We sometimes face the below error on our production servers (triggered randomly).

uninitialized constant StoreModel::Types::ArrayType

            candidate = constant.const_get(name)
                                ^^^^^^^^^^

A stack trace of the above error is as below:

ArgumentError: undefined class/module StoreModel::Types::ArrayType

StoreModel::Types::ArrayType was a class present under lib/store_model/types/ directory till 0.7.0 version. The error should not appear in the latest version. Let me know if I missed any steps when we upgraded our Rails app.

Hello, please use Many instead of ArrayType, the behavior should be pretty much the same (https://github.com/DmitryTsepelev/store_model/commit/d65f45d57a5d5e5f43305b974d4a0c86c745ec7d#diff-616e8eaf5922e04790111e623d778a38a79f26f344a0953fb498439017a232f4R9)

Hey @DmitryTsepelev, Thanks for the quick response. Apologies, I forgot to mention one crucial part.

We are not including StoreModel::Types::ArrayType anywhere in our code base. Hence figuring out the issue is a bit tricky.

@DmitryTsepelev, any updates on the above concern?
