Github build action succeeded despite bad path in Xcode project file

[vishnuravi]

The build log shows the following:

2022-07-05T21:36:36.6024210Z error: Build input file cannot be found: '/Users/vishnu/code/CardinalKit/CardinalKit-Example/CardinalKit/Library/ResearchKit/CKUploadToGCPTaskViewControllerDelegate.swift' (in target 'CardinalKit_Example' from project 'CardinalKit') …

But then a few lines later it states:

** BUILD SUCCEEDED **

It is unclear why the build succeeded with a bad path.
