Version: Form 4.4.0

I have a number of forms for a clients website. We have created a custom membership provider as all the member information is housed via a third party API. As a result, we do not have any members within Umbraco.

The custom membership provider uses a GUID for the key. This key is then stored in the forms data under the table, MemberKey.

When getting the data, this throws an internal 500 error. From PostRetriveRecords, this is trying to convert the Guid to a Number (StringToNumber). Of course, this fails. (stack trace at end)

Is there a way we can skip/by pass getting the member information when viewing the entries? Or if anyone has had a similar issue, what was the solution they found to get around this?

Thank you for your assistance.
