Issue description and reproduction steps

A JSON parser is used to extract error messages and other info from responses. However, it appears that some unexpected format is being sent for some errors, such as when there are too many requests:

We need to investigate why these responses aren't getting parsed, and ensure that error messages are correctly relayed from the server to the customer and MSAL provides provide meaningful messages.
