Start in plugins/network_vis/public/network_vis.js and inspect the imports for ui/vis/editors/default/schemas and ui/vis/vis_types/angular_vis_type. Reproduce the Kibana 7.7.0 build failure, then verify that the network visualization plugin builds and Kibana starts without these missing-module errors.
