Coral composite multifield does not support coral autocomplete OOTB component

[#1]

Hi All,

I have created a cq:dialog in aem6.3 with composite multifield which has one text field and autocomplete textfield.  When I change the multifield resource type from granite to coral, the autocomplete text field throws an error in the console when I type in.

Below is my dialog structure,
