Hello,

Attempted to file a 10-K today and received the following python exception that halted the filing. This is replicable in Arelle 2.25.0 but previous versions  did not error in this way (unfortunately I did not note which versions before updating to troubleshoot).

[exception:AttributeError] Instance validation exception: 'NoneType' object has no attribute 'localName', instance:  *************.htm - *************.htm
Traceback (most recent call last):
  File "D:\a\Arelle\Arelle\arelle\Validate.py", line 122, in validate
  File "D:\a\Arelle\Arelle\arelle\ValidateXbrl.py", line 405, in validate
  File "C:\Program Files\Arelle\plugin\validate\EFM\__init__.py", line 349, in validateXbrlFinally
    validateFiling(val, modelXbrl, isEFM=True)
  File "C:\Program Files\Arelle\plugin\validate\EFM\Filing.py", line 4576, in validateFiling

AttributeError: 'NoneType' object has no attribute 'localName'


There were three facts that needed to be removed in order to get a clean Arelle result. All three facts had a dimensions using ' RevenueRemainingPerformanceObligationExpectedTimingOfSatisfactionStartDateAxis'  so it seems that the error occurs when validating DQC Rule 0076.

If there is some new way of correctly handling DQC 0076, would appreciate any guidance.

This is fixed in Pull Requests which were merged into [master] tonight, and a hot-fix at SEC planned for tonight.
