Having some trouble with the Solidus Paypal Commerce Platform gem. Just upgraded this site to Solidus 3 and Ruby 3 and noticed this after, but can't confirm it was working before since the last Paypal payment processed was back in September and reverting all my changes doesn't seem to fix it. We're using Hatchbox Classic with nginx in case that may be relevant. Currently during checkout if someone selects Paypal as the payment type and clicks the Paypal button, the Paypal popup opens and immediately throws an alert "There was a problem connecting with PayPal." The console shows:

#<OpenStruct name="AUTHENTICATION_FAILURE", message="Authentication failed due to invalid authentication credentials or a missing Authorization header.", links=[#<OpenStruct href="<https://developer.paypal.com/docs/api/overview/#error>", rel="information_link">]>

Traced it back to models/solidus_paypal_commerce_platform/gateway.rb in the

create_order

block. I added a

binding.pry

before

@client.execute(request)

and the request doesn't seem to have any bearer token. If I do

request.headers["Authorization"] = "Bearer (redacted bearer token)"

it works. Not sure how the gem would normally handle the authentication but if anyone has any pointers, please let me know.

@Tyler Kocheff, does it work with

07e58774090add0660b175bfaf22f0925884f6b3

but not with

c4e7fb9b3a7c48cb4f90129b725ad46995822bfb

?

Actually, it works with that one too. I had assumed that change might have broken it, but it looks like it's the next one that it's broken on:

fee386c89cc76300fab98e0e17a31c9ceac5e4f9

That commit has something relevant: renaming

authorizationString

method to

authorization_string

. Is it possible that you are using the old name somewhere? Do you have something for

grep -r authorizationString .

in your project root?
