Additional information

If the front matter is changed to

---
aliases: [author2007, another alias]
---

it works.

I conclude that it is the @-symbol in the first alias that breaks all aliases for this note.

The Obsidian documentation (Add aliases to note - Obsidian Help) doesn’t mention any forbidden characters in aliases, so I’d assume that the same rules apply as to file names (where @ is allowed). This is why I file this as a bug rather than a feature request. If it is not a bug, please move it to #Feature-requests. In that case I would suggest adding a note to the documentation about forbidden characters.

As for the need of this: many people use aliases starting with @ to refer to the citekey of their references (alias: @author2007) still works!). This bug (?) makes it impossible for them to use more than one alias for those references.

I think I figured it out. It works when you escape strings with forbidden characters using quotation marks, like this:

---
aliases: ["@author2007", another alias]
---

So perhaps this could be added to the documentation at Add aliases to note - Obsidian Help?

In any case, the bug turned out to be none, so I’m moving this topic to #get-help

While experimenting, I also noticed that having more than one aliases: line in the header will break all of them (i.e. none is recognized as a valid alias). It would be great to have a setting to change this behaviour to “use last” or “use first” instance of the tag.
