ACS Commons - Composite Multifield - Multifield attempted to extend a non-truthy object

[nj2]

Hi Community members, 

Has anyone come across this console error:"Multifield attempted to extend a non-truthy object"

We are using custom composite multifield wrapper implemented with ACS Commons multifield. 

I'd greatly appreciate any insights or pointers you can share to help resolve this issue. 

AEM 6.5.17

ACS Commons - 5.3.4

Thanks

@nj2 Are you using Coral UI2 or Coral UI3 multifield? Can you also share the dialog structure to analyze?
