What happens?
TypeError: Cannot read properties of undefined (reading 'value')

at setup (ExpiryField.vue:165:3)The relevant part is:
if ( mw.util.isInfinity( given ) ) { expiryType.value = 'preset-duration'; // Set the "infinite" option that exists. presetDuration.value = presetDurationOptions.find( ( option ) => mw.util.isInfinity( option.value ) ).value; // <-- } // ...
Apparently, the code assumes that there would be an "indefinite" option, but this is no longer true following T401823.
What should have happened instead?
There should have been no errors.
