PASS_HOOK_FAILED

What happened#

One of the three hooks that run after a pass, score, accept or report, raised an error or returned a value Forge cannot use.

Common causes#

• The hook raised an error. The message names the file, the line and the function.
• score returned a value that is not a finite number.
• accept returned a value that is not True or False.
• report returned something that is not a dict of names to numbers.

What to do#

Return a finite number from score, True or False from accept, and a dict of names to numbers from report.

Example#

strategy.py, line 44, in score: score raised ZeroDivisionError: division by zero [PASS_HOOK_FAILED]
strategy.py, in score: score returned nan, not a finite number [PASS_HOOK_FAILED]
strategy.py, in accept: accept must return True or False, got int [PASS_HOOK_FAILED]

The wording of the message depends on your file, and the code does not. A value Forge cannot use has no line of its own.
