This error occurs when an @stillwind-require-properties directive in your
stylesheet has invalid syntax, such as an incomplete custom property name. The
directive lists the registered custom properties that a utility needs.
Reported
.card {
@stillwind-require-properties tw-rotate-x;
transform: var(--tw-rotate-x);
}SW14003: invalid Stillwind property requirement at byte 9660
Fixed
.card {
@stillwind-require-properties --tw-rotate-x;
transform: var(--tw-rotate-x);
}How to fix
Write each name in full, including the leading --, as in the example.
A valid name that no registration provides is reported as SW14005. An invalid directive inside a utility from a plugin is reported as SW14004.
