in both of them it has pointed to a js file with a coded name (i.e. plugin-third-party-66034ae1bc6977c5ec45dcf7adb5f8f9799ab0ff261ffd958c9425a34a956605.js).
is it possible that the plugin name is also mentioned in the error log?
My understanding is that the file linked contains the JavaScript for every plugin installed on the forum - Recommander just happens to be the first one in the file.
If you do a Ctrlf for define("discourse/plugins you’ll see many plugins.
