No suitable records were found verify your bundle identifier is correct
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.
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.
Just check that app you configured on iTuneconnect is having same bundle identifier that you are using to upload app.
