Looks like VAT does not like the lisp_eid_table_dump API call in 20.05. It dies when I have some LISP config in VPP and then execute lisp_eid_table_dump API. Here's how to reproduce it:

 

1. Run the attached API trace file (lisp_eid_table_dump.api) to re-create the LISP config in VPP

2. Execute lisp_eid_table_dump API from VAT
