MU-Migration cannot get tables

I am just trying out Local - again, after poor performance of the previous version (for me).

I created a new site and, mu-migration os important for me so I tried it out. SSH and trying
wp mu-migration export all starter gives the following messages - any ideas?
Exporting site meta data…
Exporting users…
Exporting tables
Error: Unable to get the list of tables to be exported
