BSM related_services API endpoint truncates long sys_id lists, returns 400 error as a result on Dependency Viewer - Known Error

BSM related_services API endpoint truncates long sys_id lists, returns 400 error as a result on Dependency Viewer Description If a large list of nodes is present in the Dependency Viewer, the Related Services tab in the details pane can potentially be unusable as too many records are being sent in the REST call to the related services API, which only accepts parameters up to a certain length. The rest of the record ids are being cut off and as a result the REST call is badly formed, resulting in an error instead of any related services being returned.

Steps to Reproduce

Open Dependence View on a CI with large number of child and parent nodes (e.g. business critial server CI) and have map depth (max levels) = 3

Workaround The correct fix is to convert the call to make a POST request as opposed to GET, as there is no limit on payload length for POST requests. That requires a change to the backend java code.

Before the fix patch/release is available, the only workaround would be reducing the depth of a dependency view to 1 (or 2 if it also returns results).
