Versions Affected:

Versions affected: PAC firmware R9.5a through R9.5d
Problem is fixed in version: FW R9.5e

Resolved In Version:

Problem is fixed in version: FW R9.5e


Symptoms:

If a request's* syntax is not quite right, you may receive unexpected results, but no error code.

For example, this request:
/api/v1/device/strategy/tables/floats/TableFloat?elementnum=1
appears to request just one element, but returns all elements instead.

The problem is that elementnum should have been numElements. Instead of a list of all elements, a -36 error should have been returned.

*A request is a URL that follows the syntax for the SNAP PAC REST API.  It's also known as an "endpoint."
