How can I fix the Fedex authentication error in the test environment?

Fixing a FedEx authentication error in a test environment typically involves ensuring that your test credentials are correctly set up and used. Here are some steps to help you troubleshoot and resolve the issue:

Verify Test Credentials: Ensure that you have obtained the correct Test Account Number, Test Meter Number, and Test Key and Password from the FedEx Developer Portal. These credentials must be included in your code.

Check Configuration: Double-check your configuration settings to ensure that the use_test_server parameter is set to True and that the correct test credentials are being used.

Update Credentials: If you're still encountering issues, you might need to request new test credentials. Sometimes, test keys can become invalid or expired. You can obtain new test credentials by logging into the FedEx Developer Portal and generating a new test key.

Contact FedEx Support: If the above steps don't resolve the issue, you may need to contact FedEx Web Services support for further assistance. Provide them with your Account Number, Meter Number, and any relevant contact information.

Review Documentation: Refer to the FedEx Web Services documentation for any additional troubleshooting steps or updates.
