[Harlowe] Getting 'unexpected identifier' while using (link-reveal:), is it just syntax?

So I've set up cheats for my project using debug-footer, and in it I want to only show the list of cheats and quick-jumps if clicked. Here is my code:

----
Debug mode is on.
(link-reveal: Reveal GOTOs)[
[[GOTO inv-test->inv-test]]
]
(link-reveal: Reveal Cheats)[
(link: 10000 inv space)[(set: $inv_limit to 10000)]
]

However the resulting footer is:

Debug mode is on.
☕ Unexpected identifier►
GOTO inv-test

☕ Unexpected identifier►
☕ Unexpected identifier►

(Sorry just copy-pasted that in, the cups of coffee are unintentional, probably something with unicode.)

If anyone can help, that would be appreciacted.
