fi-0166: Unexpected constraint {:#fi-0166}

This error occurs when you try to use a constraint where it's not expected. Typically, this is due to a named const in the wrong position.

{% include “docs/reference/fidl/language/error-catalog/label/_bad.md” %}

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0166.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}

To fix this error, remove the constraint:

{% include “docs/reference/fidl/language/error-catalog/label/_good.md” %}

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0166.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
