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 application. When I use this code to initialize the environment:

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

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

and this error as a warning in the application: error internal server error

I would like to switch to the new PayPal iOS SDK, but it does not yet offer third-party payments. Any idea what to fix these errors? Thank!

However, the question has an answer, I would like to add my two cents for future beginners, such as myself, who may find the same error.

Bundle display name info.plist .
