Task Planning does not succeed due to Invalid goal format. #8

Closed sea-bass closed 2 weeks ago

sea-bass commented 3 weeks ago

When I tried doing task planning from one of the solution files on Problem 1 by

  1. Selecting Task Planning from PDDL File
  2. Using planning/solutions/problem1.pddl as my file

The resulting task failed with this error

00:59:48;0.0004;Task Planning from PDDL File;52;Extract PDDL Goal from File;53;Success;1;Extracted goal from planning/solutions/problem1.pddl
00:59:48;0.0548;Task Planning from PDDL File;52;Task Planning from PDDL Goal;54;Failure;-101;Invalid goal format. Expected '(<goal condition>)'. Got goal '    ; Snacks are on the table    (skiros:contain skiros:Table-15 skiros:Snacks-23)'

Here is the log I saw:

Feel free to reopen if there are similar issues with the solution pddl files.
