Description

Got reports that certain valid characters in id were not handled appropriately in node.js SDK (space at the end of id for example). When testing I realized inconsistency across SDKs and even Gateway vs. Direct - so I will go through and create a baseline with end-to-end tests in all SDKs and then see how we can fix this situation (and whether we think it is important to fix vs. just better and more clear document the various constraints)
