Sabre API Error "errorCode": "WARN.RAF.APPLICATION"

Question

I am building a Travel Website. I have successful integrated the APIs for Sabre. However if I do not pass retun date in query or if return date is null I get error.

After lot of troubleshooting I decided to check on Sabre Dev studio https://developer.sabre.com/docs/rest_apis/air/search/instaflights_search/reference-documentation#/default/instaFlightsSearch

If I leave the return date empty or do not pass it. I get the same result on Sabre site as well.: { "status": "Complete", "reportingSystem": "raf", "timeStamp": "2024-03-11T11:58:15Z", "type": "Application", "errorCode": "WARN.RAF.APPLICATION", "instance": "raf-raf-blue-5f55d58779-926dx-default", "message": "No results were found" },

Though if i scroll below I can see the flights results, however my Laravel application does move ahead and and I get the same error.

How can I move ahead even with this error or fix it. Though it is also on sabre dev studio
