you are doing something wrong. the code looks fine to me

-- load JSON from file 
function loadJSONData( filename ) 
    local file = fileExists( filename ) and fileOpen( filename, true ) or fileCreate( filename ) 
    local str = fileRead( file, fileGetSize( file ) or 0 ) 
    local t = fromJSON( str ) or {resolution = {}} 
    fileClose( file ) 
    return t 
end 

It's all code of function

function loadJSONData( filename ) 
    local file = fileOpen( filename, true ) or fileCreate( filename ) 
    local str = fileRead( file, fileGetSize( file ) or 0 ) 
    local t = fromJSON( str ) or {resolution = {}} 
    fileClose( file ) 
    return t 
end

local file = fileExists( filename ) and fileOpen( filename, true ) or fileCreate( filename ) 
  

I'm not sure, I'm assuming that if the file already existed, you would get a TRUE value, and not a file element. You could also fix it by using parentheses
