Error: Cannot use object of type CRM_Core_DAO_EntityTag as array in CRM_CivirulesPostTrigger_EntityTag->triggerTrigger()

Since updating to CiviCRM 5.35.0 I'm seeing this PHP error, in particular when a webform is submitted with a new contact.

Error: Cannot use object of type CRM_Core_DAO_EntityTag as array in CRM_CivirulesPostTrigger_EntityTag->triggerTrigger() (line 38 of xxxxx/org.civicoop.civirules/CRM/CivirulesPostTrigger/EntityTag.php) this line

There's a few references to $objectRef['0']) and $objectRef['1']) in that function when this seems to be an array. Should it be calling convertObjectRefToDataArray() first? this function

Is it connected to !105 (merged)
