<ActiveSupport::MessageEncryptor::InvalidMessage: ActiveSupport::MessageEncryptor::InvalidMessage Error when deploying to Heroku Rails 5.2.3

Question

I'm having a good bit of trouble deploying my React on Rails App to Heroku. I have read and attempted countless posts on how to fix the secret_key_base and rails_master_key issues:

ActiveSupport::MessageEncryptor::InvalidMessage

Running a rails server in production locally (InvalidMessage error)

Not having any luck with any of these and there seems to be a good bit of debate over a lot of practices used to fix these issues (judging by the answers I've read).

Here's the error I'm getting in my Heroku logs:

Would appreciate any help and can provide any details I might have left out. I'm relatively new to Heroku so I might just be overlooking something obvious, and I apologize if that is the case!

Answer 1

In my case I was using an old outdated master key

What I did is removing config/credentials.yml.enc then updating my config/master.key with the new key then ran EDITOR="vim" rails credentials:edit and it was all good

Answer 2

1. remove this file:

$ rm config/credentials.yml.enc

2. re-generate this file:

$ EDITOR="vim" bundle exec rails credentials:edit

then try again

Answer 3

IN my case we had a multi-environment credentials setup.

One for development, staging, and production.

The master.key works for the main

 credentials.yml file

The other environments have there own key, so for staging we used the staging.key in the

RAILS_MASTER_KEY ON heroku.

For normal use try the following :

copy data from credentails.yml file delete credentials.yml and master.key

Use Editor='code --wait' rails credentails:edit relplace code with your editor name.

paste credentails data in credentails file.
