The reason for getting the error warning is the use of API that is set on http but you are connecting it with https. We have a few solutions to help you fix the error in an efficient way.

By switching the https to http, the error warning will be resolved as locahosts are never under https by default, though you can also set the localhost server to https.

Solution 2 – Check the link of the URL

Another solution to resolve the error is to ensure that the link of the URL that you have used in the development should be the same that is used for postman testing. Both the url links should be identical. If http is what you used during the development, then you need to use the same when you are testing with the postman. You need to remember that https and http are different and also treated differently by API.  Having both identical can fix the error warning.
