Ngrok proxy for local development not working

Here is proof the file apple is looking for does exist

Hi @cocomishra,

You wrote:

The type error above may be unrelated to your merchant domain validation file, and both may have different underlying causes. The error:

TypeError: undefined is not an object (evaluating 'applePaySession.completeMerchantValidation')

This means the applePaySession is undefined at the point the callback fires. This is typically a scoping or session creation issue, not an ngrok issue. For example:

• Session variable is out of scope: The most frequent cause is that the ApplePaySession object is declared inside a block and is not accessible in the onvalidatemerchant callback.
• Session was never created successfully: If new ApplePaySession() throws or returns undefined, all subsequent calls on it will produce this error. Guard against this in your logic with console logs to help surface this error while debugging.
• Merchant validation response is malformed: Even if the session exists, if the merchant session payload returned from your server is incorrect, completeMerchantValidation will fail. Make sure your server passes back the raw, unparsed JSON from Apple's servers.

Now, to the potential merchant domain verification issue. Please see the following technote for more information:
