Check the Deployment Settings: Ensure that the Suitelet deployment is set to be available without login. If it's not, users will receive a 500 error with the message "You are not allowed to navigate directly to this page." when trying to access the Suitelet without logging in. 2. Check the SuiteScript Version: Make sure that the SuiteScript version used in your Suitelet is compatible with your NetSuite version. If you're using SuiteScript 2.0 and getting an 'INVALID_API_VERSION_FOR_FORM' error, it might be because your form in production has SuiteScript 1.0 applied to it. 3. Check the Script Status: If you're getting a message like "That Suitelet is invalid, disabled, or no longer exists.", it might be because the Suitelet is in testing mode. In testing mode, the Suitelet will only run for the user that owns the script. Make sure the deployment is active, and the script is live. 4. Recreate the Script: If none of the above solutions work, you might need to delete the script and deployment and recreate them. This can solve issues where the script or deployment has become corrupted or invalid for some reason. Remember to always test your Suitelets in a sandbox environment before deploying them to production to avoid any unexpected issues.
