Type is not supported for RuleActionDefinitionParameter

Hi,

I am trying to create RuleActionDefinitionParameter with custom item type like below,

 INSERT_UPDATE RuleActionDefinitionParameter;definition(id)[unique=true];id[unique=true];priority;name[lang=en];description[lang=en];type;value;required[default=false];validators
 ;y_change_delivery_mode;replaceable_delivery_mode;900;replaceable delivery modes;the delivery modes to be swapped when promotion applied;ItemType(DeliveryModeGroup);;;

I am able to see that param in action but on selection I am getting error like below,

And in console I am seeing this error,

Any clue why I am getting this error.

Thanks
