Hi, I’m at creating an ePub once again and run into an error:

The error is in this function:
local function relocateimages(imagedata,oldname,newname,subpath,rename)
local data = io.loaddata(oldname)
if data then
subpath = joinfile("..",subpath)
report("relocating images")
local n = 0
local done = gsub(data,[[(id=")(.-)(".-background%-image *:
*url%()(.-)(%))]], function(s1,id,s2,name,s3)
local newname = imagedata[id].newname
-- #### imagedata[id].newname throws the above error
if newname then
if subpath then
name = joinfile(subpath,basename(newname))
else
name = basename(newname)
end
-- name = url.addscheme(name)
end
if newname then
n = n + 1
if rename then
name = joinfile(subpath,addsuffix(id,suffix(name)))
end
return s1 .. id .. s2 .. name .. s3
end
end)
report("%s images relocated in %a",n,newname)
if newname then
io.savedata(newname,done)
end
end
return images
end
My prd_MBL-pub.lua looks like:

What’s wrong?
looks like an old mtx-epub, the latest one has a check
