Apparently there are known cases where projects execute a UI5 Tooling build on a previous build result. In this case we will minify previously created (and already minified) preload bundles.
The source maps associated with these bundles are index- (or "sectioned") source maps. Some section maps (for example those generated during the bundling) might be lacking the "names" array. Since this is fine for regular source map, I assume this should be fine for index source maps too.
Apparently, Terser fails to parse these source maps as of today. Therefore we will manually add the missing "names" array for the time being.
I proposed an upstream fix here:
