SSOV2 modifies the payload for big post requests and since the server does not understand this, so all such transactions fail.
SSOV2 is a very common use case for APM. Many applications are configured with SSOV2. Any large post in such case will fail.
Large post requests using form based SSO.
This issue has no workaround at this time.
The fix essentially does not modify the payload so the applications have no problem.
