[HTCondor-users] Comparing evaluation result with "classad.Value.Error" throws error

[Ceyhun Uzunoglu <ceyhun.uzunoglu@xxxxxxx>]

Dear htcondor community,

 

Iâm upgrading my codebase to htcondor v9.0.0 from v8.7.9.

As it is mentioned in this comment[1], comparison of âclassad.Value.Errorâ throws âclassad.ClassAdEvaluationError: Unable to evaluate _expression_.â exception.

What do you suggest to use instead of line-3. Iâm trying to check evaluation result is not a classad.Value.Error.

 

1. value = ad.eval(key)

2. if isinstance(value, classad.Value):
3.    if value == classad.Value.Error:

 

Kind regards,

Ceyhun Uzunoglu
