presentPaymentSheet not working with live publishable key

I am using this library in one of my react native app for iOS to receive payments using credit cards only. The library work fine for test keys but as soon as I start using publishable live key, It starts giving me error: Error code: Failed No valid API key provided. Set STPAPIClient.shared().publishableKey to your publishable key, I double checked the publishable key from my stripe account and it is the correct live key. Here is the code

<StripeProvider
        publishableKey={
          'pk_live_XXXXXXXXXX'
        }>
<App />
      </StripeProvider>

Because in the above code as soon as I change the publishable key from live key to test key, everything starts working as expected. Is there any setting that I am missing in case of Live in iOS apps?

Please help

merchantIdentifier is only necessary for Apple pay. If everything works correctly, and the only thing you change is the actual text values of the publishable keys, then I would double-check that key if I were you. You may also want to confirm that the value you’re getting from your server is the value you’re expecting it to be

It is resolved, yes @charliecruzan-stripe you are absolutely correct, due to copy paste one of the character was coming in different format somehow, due to which it was failing, it was looking correct but was getting read incorrectly. Now its working fine. Apologies for wasting everyone’s time. Thanks again.
