AFR issue - error when accessing report - "The message received from the server could not be parsed. "

Issue when trying to access an AFR report for only one of our users.

Forms:PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

We have isolated this issue, and have implemented a workaround.

  1. We created a 2nd user id, and assigned the same permissions to the new user id as the userID with the issue.

  2. We also used exactly the same password as the user with the issue.

  3. This generated the same error.

It was then determined that a “<” was included in the account password, causing the html parsing issue. We proved this was the issue by removing the “<” from the password, thus resolving the issue.

Long-term fix - implement Https for AFR.

I’d report that to Epicor… they should open a bug ticket and fix that.
