Gem clashing

[AbdullahAli]

Hey, when I use the following gems and version, I get the following error:

gem 'devise_token_auth'
gem "active_model_serializers", "~> 0.8.1"

if I update active_model_serializers to version 10, then devise_token_auth works. Looks like devise_token_auth is clashing somehow, any idea how to fix without changing the active_model_serializers, since it involves big changes to my app

NameError at /auth/sign_in

> uninitialized constant DeviseTokenAuth::ApplicationController::ActiveModelSerializers

0.8.1 has 4 years, if there was the other way around (like we have to update to the last active_model_serializers version), we would do it.

So you have 2 options:

• Update the active_model_serializers gem, or
• Override is_json_api and replace the code with the previous version of ActiveModelSerializers. You can do a concern in your code and add it to each devise token auth controller.
