    repoupdater: fix error handling responses (#49740)
    
    I'm not sure who/how this got introduced, but these two instances of
    error handling seem clearly incorrect without a return statement (all
    others in the file have this.)
    
    This is obscuring an error that people are getting in App; this won't
    fix the error but hopefully will let us see what it is..
    
    (Thanks Quinn for spotting this)
