133: Metadata name expected after @

The squirrel @ marks metadata in the text and is required to be followed by a metadata name which has been declared in a metadata declaration. However, @ is not followed by a metadata name in your case.

Solution

Make sure the @ is immediately succeeded by a declared metadata name as in the following example:

@ author: John Doe

This excerpt was written by @author in 2017.

You can also enclose the metadata name in backticks to separate it from other characters like the ellipsis in the next example:

This excerpt was written by @`author`…

If you did not mean to use metadata within the text, but want to use a literal @, you can prepend a backslash: \@
