I can not reproduce the issue local , can you provide reproduction example ?

[annfredin]

Please use the below repo
https://github.com/annfredin/mfe-manifest-example.

Usecase:
Once host app loaded the remote app, we may required to re-register/override the remote entry, when new version deployed(remote app). what is the way to update manifest URL.

In Host app remote1 page, i am trying to registerremote.

1. got warning as [ Federation Runtime ]:The remote "remote1" is already registered. If you want to merge the remote, you can set "force: true".

2. when register with force option, exception occured.
   Uncaught TypeError: Cannot delete property 'remote1' of #.
