229: Metadata name expected after ->@

You have linked to a file with a combination of arrow and squirrel ->@ which marks a metadata link and is expected to be followed by a metadata name. But ->@ is not followed by a metadata name in your case.

Solution

Make sure the ->@ is directly followed by a metdata name that was declared with a link as value as in the following example:

@ Powell: ->/photos/bear-park/20190503-496.jpg

[i:A sloth bear sniffs for termites.]->@Powell

If you want to create a regular link to a file whose name is an @ sign – whatever that might be good for –, you can prepend it with a backslash ->\@ or enclose it in backticks: ->`@`

If you did not mean to create a link to a file at all, you can also prepend a backslash to the arrow: \->\@
