Facebook publicize connection keeps failing

[malinajirka]

Related to #8115

Expected behavior

When the user tries to connect a Facebook account with no pages to their site the app displays meaningful error with explanation why it can't connect to the account.

Actual behavior

When the user tries to connect a Facebook account with no pages to their site the app displays generic error which isn't very helpful.

Steps to reproduce the behavior

1. Try to add a Facebook account with no pages.

Notes
I think the issue is on the following line -> we don't show the chooser dialog when there is exactly one connection and we assume this connection will work. However, if this is a User Profile connection and the service (such as Facebook) doesn't support other than external connections, it'll fail with meaningless error message.

I think we should modify the check to if (... || jsonConnectionList.length() == 0) and here propagate a specific error to the UI and show a meaningful message.

That sounds like a great solution, @malinajirka. If I recall correctly I thought we didn't get a profile back at all if there was no pages. Looks like that's not the case.

Tested and confirmed (11s) using WPAndroid alpha-156 (12.0 alpha) on Pixel 3 Android 9. In my case I tested with a Facebook account that has a Page that is unpublished in Facebook > Page > Settings > General > Page Visibility (screenshot).

I couldn't get the app logs to save for some reason (or I missed them) but I caught a screenshot:

This came up again in 12.3 beta testing. I found that I was unable to connect Facebook or LinkedIn—the result was the same for each: "An error occurred". My test Facebook account does have a Page but it is unpublished (screenshot).

Here is a ticket with a user experiencing this issue. Getting more info from the user to understand the issue 2047729-zen.

@osullivanchris 2047729-zen mentions a different case because they are trying to connect a Facebook account with a page whereas this bug is about trying to connect a Facebook account with no pages. If you can open a new issue with a quick list of steps to reproduce then I will check it out!

The LinkedIn failure does not seem to be related to the Facebook error. I created a separate issue for it: #10252.
