Matching capitals and underscores between curly brackets

I'm trying to extract patterns like {THIS_PATTERN} from something like the following:

.intro-header {
    padding-top: 50px; /* If you're making other pages, make sure there is 50px of padding to make sure the navbar doesn't overlap content! */
    padding-bottom: 50px;
    text-align: center;
    color: #f8f8f8;
    background: url(../img/{BG_IMAGE_0}) no-repeat center center;
    background-size: cover;
}

In this case it would be {BG_IMAGE_0}.

I can't figure out what's wrong with my regex: \{[A-Z_]*\}

I have a regex101 fiddle here: https://regex101.com/r/KF5Sz6/2

This should work:

\{[A-Z_0-9]*?\}

You didn't seem to take into consideration the "0".

By doing it like so *?, you also make it non-greedy, which should prevent interference from other { }, on the same line, were you to stumble upon any in your future projects.
