Breakpoint mixin compilation error - sass

Question

I have been working on a project which involves a bit of Sass and breakpoint. I am using gulp to handle the workflow.
Things have been working fine until I got this compilation error which is hampering further flow. I am sharing the code as well as the error that I received on Gitbash.
_nav.scss
a{
color:$navForeground;
text-decoration:none;
text-align:center;
display:inline-block;
padding:10px;
font-size:1.5em
#include breakpoint(max-width $small){
font-size:1.2em;
span{
display:none;
}
}
}//a
This _nav.scss gets compiled into styles.css. Below is the error that I am getting in bash.
Compilation failed in 1 files.
[16:32:22] { [Error: error components/sass/style.scss (Line 25 of C:/Users/user/Desktop/responsive/components/sass/modules/_nav.scss: Invalid CSS after " font-size:1.5em": expected ";", was "#include breakp...")
Compilation failed in 1 files.

fileName: 'C:\\Users\\user\\desktop\\responsive\\components\\sass\\style.scss',

Would be really appreciative if someone could help. Thank you in advance.

You forgot a semicolon after font-size: 1.5em:
font-size: 1.5em;
#include breakpoint(max-width $small) {
