ROOT CAUSE

After tracing the clipboard ,pyWorkPage structure for reference property looked empty.

The NumLevelsFromRef is Unknown and it is not a NamedPage link, which was being defaulted to CommonTLP in earlier releases. This was broken in 7.2.2

RESOLUTION

HFix-35901 is created for this issue .

As part of the Fix NamedPage Link has been defaulted to Common TLP ,this issue is fixed in 7.3.1 .

Later on user have tried to search historical work objects and they failed with below exception
