Having major issues creating an invisible explosion

Hello again everyone. I am eleven years old and a novice at Corona. I have a large amount of code for creating an invisible explosion. However, after adding the final event listener, terminal says that it is trying to call method "getOrCreateTable" and says it is a nil value. Oddly, I never included tables in my code. It does the strack traceback thing and says
[C]: in function 'getOrCreateTable'
?: in function 'addEventListener'

One thing to note is that when I replace 'background' in the final event listener with 'Runtime', it replaces all instances of 'getOrCreateTable' with 'respondsToEvent'. Here is my code:

local physics = require("physics")
physics.start()
physics.setScale(40)
display.setStatusBar( display.HiddenStatusBar )
 
local background = display.newImage( "background.png", 0, 0, true )
background.x = display.contentWidth / 2
background.y = display.contentHeight / 2
 
local floor = display.newImage( "floor.png", 0, 280, true )
physics.addBody( floor, "static", { friction = 0.5 } )
 
local function onLocalCollision( self, event )
        if ( event.phase == "began" and self.myName == "circle" ) then
                local forcex = event.other.x-self.x
                local forcey = event.other.y-self.y-20
                if (forcex < 0) then
                        forcex = 0-(80+forcex)-12
                else
                        forcex = 80-forcex+12
                end
                event.other:applyForce( forcex, forcey, self.x, self.y )
        end
end
 
local crates = {}
 
for i = 1, 5 do
        for j = 1, 5 do
                crates[i] = display.newImage( "crate.png", 140 + (i*50), 220 - (j*50) )
                physics.addBody( crates[i], { density = 0.2, friction = 0.1, bounce = 0.1 } )
        end
end
 
local circle = ""
 
local function setBomb ( event )
        if(event.phase == "began") then
                circle = display.newCircle( event.x, event.y, 80 )
                                circle.myName = "circle"
                circle.setFillColor( 0, 0, 0, 0 )
                physics.addBody( circle, "static", {isSensor = true} )
                circle.collision = onLocalCollision
                circle.addEventListener( "collision", circle )
        end
                if(event.phase == "ended") then
                circle.removeSelf()
        end
end
 
background.addEventListener( "touch", setBomb )
 
physics.setDrawMode( "hybrid" )

Also, I created a small build.settings file that probably has no importance in the matter, but just to be thorough, here's what little code is in it:

settings =
{
        orientation =
        {
                default = "landscapeRight",
                supported =
                {
                        "landscapeLeft", "landscapeRight"
                }
        }
}

Hi try replacing this:

background.addEventListener( "touch", setBomb )

with this:

background:addEventListener( "touch", setBomb )

Let us know!

Thanks a lot. Apparently I did that with a lot of the function calls. Lol. Thanks. ;)
