No suitable records were found verify your bundle identifier is correct
Solution 1:
Just found the Error. I used one capital letter in bundle id. but I have used small letters in Xcode's bundle id. now I changed that as like in the app id. and now I successfully uploaded my app to Appstore Connect.
Solution 2:
generally this happens when you have not created your app from apple developer account->iTunes Connect->Click on My App->click on plus sign (+)->New App->And fill up the whole info and Choose Your Bundle Id for the app you are uploading now.
