Wrong parameter type: options.customRecord is expected as object.

when working with

render.mergeEmail

? Getting it with this code:

var template = render.mergeEmail({
            templateId: params.templateId,
            customRecord: {
                type: "customrecord_hosting",
                id: params.eventId
            }
        });

where

params.eventId

is

"51"

and

params.templateId

is

"20501"
