rails console error due to credentials.yml.enc configuration

In this question, either Cloudinary or database was searching for a problem, and the credentials.yml.enc configuration was a problem, and a new problem appeared.
In this configuration,

Configuring credentials.yml.enc: 1

#cloudinary:
cloud_name —dnjhb66ti
api_key —195688713482412
api_secret —iw3rQu616JzDCL0-qxM-AarC6X0

I'm using
in Cloudinary.yml. <%=Rails.application.credentials.cloudinary[:cloud_name]%>
cannot be substituted for .
So,

Configuring credentials.yml.enc: 2

cloudinary:
　　cloud_name —dnjhb66ti
　　api_key —195688713482412
　　api_secret —iw3rQu616JzDCL0-qxM-AarC6X0

I tried to make sure it was configured in rails console by setting it to
The following error occurred and could not be verified.

/home/ubuntu/.rvm/gems/ruby-3.0.0/gems/cloudinary-1.0.85/lib/cloudinary/helper.rb:254:in `block included': undefined method `alias_method_chain' for ActionView: Base: Class
Did you mean?alias_method(NoMethodError)

I am investigating this error, but it is difficult to determine the cause.
Setting credentials.yml.enc: Is it wrong to write 2?
Or is the description of other files disturbing me?
