Internal Server Error with PayPal MPL

Question

I am trying to use PayPalMPL 2.1.7 for iOS to accept third party payments in my app. When I use this code to initialize the environment:

[PayPal initializeWithAppID:@"APP-80W284485P519543T" forEnvironment:ENV_SANDBOX];

I get this error in the log: Checking Error******************** Posting Error: -1

and this error as an alert in the app: Error internal server error

I would love to upgrade to the new PayPal iOS SDK, but it doesn't offer third party payments yet. Any idea what will fix these errors? Thanks!

However the question has an answer, I would like to add my two cents for future beginners like me who may found the same error.

Just add Bundle display name in your info.plist of your project as an empty.

Here's the screenshot.
