Is your feature request related to a problem? Please describe.

The error_mode determines how the processor handles errors that occur while processing an OTTL condition. The current default value is propagate, which can result in valid data being dropped.

Describe the solution you'd like

To improve resiliency, we could changing the default value to ignore. In this mode, errors are logged for visibility, but valid data is preserved, and processing continues with the next condition.

Note: This would be a breaking change and should be rolled out using a feature gate.

Describe alternatives you've considered

Keep it as it's.
