getAccessToken throws "TypeError: Cannot read property 'tokenType' of undefined" when third party cookies are blocked

Library versions

• react-aad-msal: 2.3.5
• msal: 1.3.2

Describe the bug When third party cookies are blocked, I receive an error when using getAccessToken:

"TypeError: Cannot read property 'tokenType' of undefined at new AccessTokenResponse (AccessTokenResponse.js:42) at _callee2$ (MsalAuthProvider.js:373) at tryCatch (runtime.js:45) at Generator.invoke [as _invoke] (runtime.js:265) at Generator.prototype. [as next] (runtime.js:98) at asyncGeneratorStep (MsalAuthProvider.js:72) at _next (MsalAuthProvider.js:94)"

Expected behavior I would expect that acquireTokenSilent would run, return an error and then acquireTokenPopup or acquireTokenRedirect would run.

To Reproduce Steps to reproduce the behavior:

1. Block third party cookies on chrome
2. call 'getAccessToken'
3. See error

Desktop (please complete the following information):

• OS: Windows
• Browser: Chrome
• Version 83.0.4103.106

I see this error too when third party cookies are blocked. I noticed an issue has already been filed for the underlying MSAL library:

I hit this using Google Incognito
