Trying to integrate Shipstation with Magento 2.4.4. The extension is version 2.3.1 from the Magento marketplace. I'm getting the following error in the admin area.
Deprecated Functionality: error_log(): Passing null to parameter #1 ($message) of type string is deprecated in /home/public_html/magento/vendor/auctane/api/Model/NoConfigNotification.php on line 32
Looking at NoConfigNotification.php, I can see the configuration is supposed to be done from my shipstation.com account. I have tried setting up the store integration there, but I get a 404 error. I can see the APIs in swagger. I'm able to manually hit the GET API (v1/auctane/configure). I figured out from looking at Authenticator.php that I needed to pass 'ShipStation-Access-Token' in the header with the generated api key as it's value. I tried with cURL and get a 200 OK. I'm also able to hit the POST API and pass dummy values which make the above error go away. So, it seems the APIs are working. I'm not sure why Shipstation is getting a 404. Any ideas how to get this working?
