[BUG] "Country Code must be a string"

[BrowserApi]

Describe the bug

I completed all the steps as instructed in the README, but I'm receiving this error when I click Openprovider logo to import TLD lists.

To Reproduce

Utilities > Regisitrar TLD Sync > OpenProvider

Expected behavior Instead of Importing TLD, it is showing "Country Code must be a string"

1) I tried rebooting server 2) Tried with SandBox Credential and Live account credential 3) I tried adding 6+ Currencies in WHMCS with latest exchange rate (USD, EUR, INR etc..)

• This includes EURO (The currency of Sandbox account)
• Tried Running cron ( DownloadTldPrices.php ) for Importing TLD 4) Met All PHP Requirements mentioned in README 5) No Logs are showing in OpenProvider Module 6) Im not using any other registrar 7) Clean install of WHMCS 8) I dont have any other Module or anything related to Currency

Screenshots Error: OpenProvider Module Log: System Module Log when this Error Occurs:

Server info:

• WHMCS Version: 8.10.1 (Latest)
  • Distro: Almalinux 8 x86
  • PHP: 8.1
  • Web server: Lightspeed (Non Commercial- Open Lightspeed)
  • OpenProvider Module Version: Version 5.8.0 (Latest)

Additional context I already have some experience of installing OpenProvider for some client's WHMCS and it was working fine till this day.

update: ISSUE SOLVED ✅

What i did to solve:

1) 'Deactivated' and 'Activated' OpenProvider again in 'System settings > Domain Registrars > OpenProvider'

2) Ran the cron "/modules/registrars/openprovider/cron/DomainSync.php" manually via url https:// { WHMCS URL } /modules/registrars/openprovider/cron/DomainSync.php

3) Then I ran the TLD Import cron via ssh 15 13 * php -d max_execution_time=0 modules/registrars/openprovider/cron/DownloadTldPrices.php 4) Tried Importing Again Utilities > Registrar TLD Sync > OpenProvider

Thats all.. Have a nice day!
