AuthenticationClient.getProfile returns as string text instead of a parsed JSON

[polad]

I'm using AuthenticationClient.getProfile() function to retrieve user info as a Promise instead of a callback like so:

authClient.getProfile(credentials).then(userInfo => { ... })

And the promise resolves userInfo object to a String text instead of being parsed into JSON. Is there a setting or a flag that I'm missing somewhere in the Client config? This happens on v2.6.0. I can confirm that I didn't experience this before with version 2.3.1
