No UI parser available for adapter "${type}".

Error message

No UI parser available for adapter "${type}".

What it means

Capability guard on GET /api/adapters/:type/ui-parser.js: the adapter package does not export a usable self-contained UI parser module, so there is no custom run-log parsing script to serve and the route reports the absence instead of serving a stub.
