Creating pin references - error when trying to add an alias with empty text

[hugo]

It looks like there is a bug when trying to create an alias for a reference:

When I click in “Add Alias”, nothing happens; and when I press enter, an error is shown:

Because of this, I’m not being able to create pin references anymore (which consisted of adding an empty alias to a rem reference).

Yes I have been able to reproduce this as well, looks like the other Pin bug is also related to this.
Alias function seems to have been broken, which is causing both the bugs.

@Martin this is the error that you were searching for I believe?

Thanks for the report! This has been fixed.
