entry/unknown-key
Front matter, or a Data file with a schema, has a key its Collection or schema doesn’t declare, or an Org Entry has a keyword that is neither a field nor one of Org’s. Unknown keys are errors, so a typo can’t silently do nothing.
Example
---
title: Pew
draf: true
---
Fix
Use the key the help suggests, such as draft, or declare the field under [collections.<name>.fields] in yuanme.toml.
