empty_segment

Summary

empty path segment

Help

each . must be followed by a field name; each [ must hold a key

Details

When this fires

A path inside {{ ... }} has a . with no field after it, or a [] with no key inside. The parser flags the dangling segment so you don't get a confusing render error later.

What to check

Every . needs a field name, every [ needs a key (string, number, or path) before its ]. Trailing dots from copy-paste are the usual culprit.
