Solutions

1. Set the named configuration key to a valid integer value.
2. Check for units suffixes or non-numeric characters in the configured value.

When it happens

Trigger: An integer configuration property holds a non-numeric value when ABFS validates its settings.

Common situations: See trigger scenarios.
