Errorhandler cpython

[sander_de_weert]

For multiple reasons, I use Cpython with pyrevit, by starting the script.py file with #!python3. 

When executing the script, I run into multiple warning. I'd like to skip these warning, by editing the PreprocessFailures method (like below). I got it working for Cpython (.NET) by adding the __namespace__ = EXEC_PARAMS.exec_id parameter to the definition of the class.

Somehow, when I run the script, when warning occure, everything is executed, but it is not possible to use Revit. The last line of the full script is printed. It only happens when I add the custom Error handler into one of the transaction. All together there are about 20 transactions/commits in the processes.

What can be the problem?

from Autodesk.Revit.DB import IFailuresPreprocessor, FailureProcessingResult, FailureSeverity
from pyrevit import EXEC_PARAMS


class SupressWarnings(IFailuresPreprocessor):
    __namespace__ = EXEC_PARAMS.exec_id

    def PreprocessFailures(self, failuresAccessor):
        failures = failuresAccessor.GetFailureMessages()
        for fail in failures:  # type: FailureMessageAccessor
            fail_ids = fail.GetFailingElementIds()
            severity = fail.GetSeverity()
            description = fail.GetDescriptionText()

            if severity == FailureSeverity.Warning:
                print(f'Warning: {description}')
                failuresAccessor.DeleteWarning(fail)
                for fail_id in fail_ids:
                    print(fail_id)
            elif severity == FailureSeverity.Error:
                print(f'Error: {description}')
                failuresAccessor.ResolveFailure(fail)
                return FailureProcessingResult.ProceedWithCommit
            else:
                print(f'geen warning en geen error: {fail}')
        return FailureProcessingResult.Continue
