npm install succeeded but adapter reload failed.

Error message

npm install succeeded but adapter reload failed.

What it means

Partial-failure in the reinstall route: the npm install of the adapter package succeeded, but re-importing the freshly installed module via reloadExternalAdapter failed, leaving the store record pointing at code that could not load. The route surfaces the inconsistency as an error.
