undefined method 'each' for an instance of String

[benhutton]

When I upgrade to 4.33.0, I get the following error when I run my specs. Everything works great in 4.32.0 and below.

Failure/Error:
       result = gateway.transaction.sale(
         amount: input.amount,
         payment_method_nonce: input.nonce,
         options: {submit_for_settlement: true},
         customer: {
           first_name: input.first_name,
           last_name: input.last_name,
           email: input.email
         },
         billing: {
     
     NoMethodError:

I would assume it's the same root cause as outlined in #253. Probably due to swapping out libxml-ruby for nokogiri.

Hi, we are looking at it right now. As @travisbell pointed out, this might all be related.

We have the same issue after upgrading from 4.32.0 to 4.33.0. Some of Braintree's methods stopped working. Thanks for looking into it.

3.4.7 :001 > Braintree::Customer.create(id: 'test-2025-10-28-v1')
:1:in '<main>': undefined method 'each' for an instance of String (NoMethodError)

        hash.each do |key, value|
            ^^^^^
3.4.7 :002 > Braintree::Customer.find('123')
:2:in '<main>': undefined method 'each' for an instance of String (NoMethodError)

        hash.each do |key, value|
            ^^^^^
3.4.7 :003 > Braintree::Customer.find(123)
:3:in '<main>': undefined method 'each' for an instance of String (NoMethodError)

        hash.each do |key, value|
            ^^^^^

Hi, we just released a fix. Please test and let us know if there are any issues.

[ArturT]

The 4.33.1 version works fine. Thank you.

[Fjan]

Yes, that works, thanks 👍. While we have your attention, you should really update the Gemfile to work with without warning on Ruby 3.3, it has been out for years now (issue).

[mohamedhafez]

@Fjan it's actually the .gemspec that needs to be updated i think, I have a pull request that does just that if you could look at it please @nalshapub #255

[benhutton]

This fixes it for me. Thank you!

[nalshapub]

@mohamedhafez Will add this to our backlog. Thanks for bumping it up.
