Hi,
I managed to get the error when I open the task - Undefined variable: board_phid.
The reason is simple - via conduit maniphest.edit API I set 2 columns via one transaction (both columns where in different projects).
{"type":"column","value":["PHID-PCOL-zbrzdpvgmni3dxgblbgx","PHID-PCOL-vrjokvtds3qw2cezu6h7"]}Transaction entry in DB ended up being something like this:
[{"columnPHID":"PHID-PCOL-zbrzdpvgmni3dxgblbgx","boardPHID":"PHID-PROJ-sk62b2ohwmhykjcusyam","fromColumnPHIDs":{"PHID-PCOL-euxtyti3j644vh6rsna6":"PHID-PCOL-euxtyti3j644vh6rsna6"}},{"columnPHID":"PHID-PCOL-vrjokvtds3qw2cezu6h7","boardPHID":"PHID-PROJ-64ywfx3axxzwsvvihkrb","fromColumnPHIDs":{"PHID-PCOL-4xqaswef4csi2k5p53mj":"PHID-PCOL-4xqaswef4csi2k5p53mj"}}]If this is split up in 2 transactions - no problem, but if it's within one - Task is unopenable via UI.
I actually haven't tested what would happen if I would send 2 columns within the same project, but I assume it will break as well.
