Missing file from RunScriptPhase when indexing

Hi,

I am browsing Webkit source code by using XCode 13, however it doesn't highlight syntax or index symbols on some files. When I enable Index Build Log, I see that it doesn't have some headers that come from RunScriptPhase:

I check again then see that those file exist in Build folder, but not Index/Build folder

How can I fix this issue?
