Hi. I've not used this patch as $options could be non-empty but still not have [''] as a key, so the issue would continue. I've committed a change to dev to resolve this, could this please be checked in your environments? (I can't recreate this issue myself sadly).

Thank you, sorry for delayed response. Using current dev and getting the same result but it's reporting line 263 now

Hi, I am also getting the warning, even with latest dev version.

I think the issue is solved with update to the operator.

Confirmed that there is no further warnings. We can merge #10 patch.

Automatically closed - issue fixed for 2 weeks with no activity.
