SDK authorization issues in a Rails (v6.1.7.3) application

Hello, I tried to contact [email protected] as the new issue template suggests, however I got a warning email that the email doesn't exist so writing here https://i.imgur.com/MmeCPqQ.png

Overview

We are currently trying to build a proof-of-concept for integrating Yoti into our product, and finding that whatever we try we are running into this error with the ruby-sdk:

Yoti::RequestError (Unsuccessful Yoti API call: 
Unauthorized: {
  "error_message": "Failed to verify signature.", 
  "error_code": "INVALID_SIGNATURE"
}):

Things we have tried

Different approaches for config.key_file_path

• Setting config.key_file_path with env var
• Setting config.key_file_path hardcoded as string
• Setting config.key_file_path hardcoded as Rails.root.join('app', 'assets', 'yoti-poc', 'poc-temporary.pem')

We noticed there is also a section in the README which says it is possible to use config.key on Heroku/AWS Elastic Beanstalk, so we also tried:

• Setting config.key hardcoded as string on single line (with and without \n linebreaks)
• Setting config.key hardcoded as string on multiline (with and without \n linebreaks)

Double checking the basics:

• Double checked the SDK ID and .pem file is of the latest key pair (we also tried generating a new key pair)
• Double checked that the relative path is correct by using an open command from project root like code app/assets/yoti-poc/poc-temporary.pem, which opens the correct file in the text editor
• When trying with env vars, double checked that echo $YOTI_KEY_FILE_PATH and echo $YOTI_CLIENT_SDK_ID prints the expected values

I suspect we are overlooking something simple, but as far as I can tell have followed the docs at https://github.com/getyoti/yoti-ruby-sdk exactly. Do you have any ideas what the issue may be?

In case its useful

• We are grabbing the key-pair from this location in the Yoti hub, with just age-estimation activated: https://i.imgur.com/wCkZphb.png
• This is how we’ve been calling the Yoti request in our rails controller: https://pastebin.com/raw/QfJiPTf7. Your docs seem to suggest /api/v1 as the API endpoint base just for ruby, however I've presumed that is a typo as:
  • (i) That returns Yoti::RequestError (Unsuccessful Yoti API call: Not Found: Not found):
  • (ii) All other languages use the base /ai/v1
  • (iii) The Endpoints table above the code snippets [here] for request creation suggest the base should be /ai/v1
