error with Accept hosted page (sandbox environment)

[erudizones1]

Hello

We use authorize.net Java SDK, latest version 2.0.1. Using JDK 11 (not 8) on Windows 10 (also confirmed this on Linux).

But running into what appears to be a bug (or we are doing something wrong).

--

We get a failed (with errors), Order Summary page in the sandbox environment
if the return URL that has more than one query parameters (delimited by &)

If we specifiy just 1 query parameter in the return URL, the hosted page seem to work with no problem (we get the Order summary screen, can enter cc number and click continue).

We posted this on developer forum 3 weeks ago, but did not get any guidance/replies.
(with screen shots of the error page, as well as the values in the debugger session)

The errors in the Hosted page can be seen in the attached image

The errors are:

SyntaxError: "" string literal contains an unescaped line break

ERROR ReferenceError: "g_errorPanelMessage is not defined"

ERROR TypeError: "this.paymentProfileList" is undefined
