NoMethodError: undefined method `stringify_keys'

[jaredmurphy]

Solidus Version: 2.5

When attempting to perform a Return Authorization, I'm getting the following error in ActiveMerchant that it is unable to stringify something that Klarna is attempting to pass over:

NoMethodError: undefined method `stringify_keys' for #<String:0x00000000092f82e0>
from /home/***/.gem/ruby/2.5.0/gems/activemerchant-1.92.0/lib/active_merchant/billing/response.rb:22:in `initialize

This seems to be getting fired from klarna_gateway/models/order.rb line 52 in update_klarna_shipments. Looks like Klarna may be expected to pass a hash or something here but is passing a string.

Any idea what could be going on here?

Stack Trace:
