NoMethodError: undefined method `default_adapter_options' for Faraday:Module

[jotolo]

Describe the bug

Failure/Error:
       Adyen::Client.new(api_key: credentials[:ADYEN_API_KEY],
                         env: credentials[:ADYEN_ENV],
                         live_url_prefix: adyen_live_url)
     
     NoMethodError:
       undefined method `default_adapter_options' for Faraday:Module

How to reproduce
If you try to initialize Adyen::Client class you will get this error

Expected behavior
Being able to initialize the Adyen::Client class

Additional context
It started with version 7.3.0 and it seems to be related to #169
When no adapter_options is specified, it triggers the before mentioned error

[ollym]

@jotolo it was added in Faraday v2.1.0 https://github.com/lostisland/faraday/releases/tag/v2.1.0

What version are you using? (Faraday::VERSION)

[jotolo]

Hi @ollym , we are using Faraday 1.10.3. This is why the issue is triggering but there is no constraint on the version needed by the library. Is it needed?

[ollym]

@jotolo yes that should be fixed but suggest you target faraday >= 2.1 in your Gemfile.

Alternatively the following should work with Faraday < 2:

Adyen::Client.new(api_key: credentials[:ADYEN_API_KEY],
                         env: credentials[:ADYEN_ENV],
                         live_url_prefix: adyen_live_url,
                         adapter_options: {})

@ollym Correct. The proposed solution works. I saw #178 was opened and it manages to solve the issue. Once that PR is merged we can close this issue.
Thanks @ollym and @Aleffio for the quick response 🤝 .
