You need to remove these lines from the library:

Code:

  for _, searcher in ipairs(package.searchers or package.loaders) do     name = "cjson"     local loader = searcher(name)     if type(loader) == 'function' then       package.preload[name] = loader       cjson  = require (name)       break     end     name = "json"     local loader = searcher(name)     if type(loader) == 'function' then       package.preload[name] = loader       cjson  = require (name)       break     end   end   for _, searcher in ipairs(package.searchers or package.loaders) do     name = "vbusprofiles"     local loader = searcher(name)     if type(loader) == 'function' then       package.preload[name] = loader       vbusprofiles  = require (name)       break     end     name = "user.vbusprofiles"     local loader = searcher(name)     if type(loader) == 'function' then       package.preload[name] = loader       vbusprofiles  = require (name)       break     end   end   for _, searcher in ipairs(package.searchers or package.loaders) do     name = "luavbuspacket"     local loader = searcher(name)     if type(loader) == 'function' then       package.preload[name] = loader       luavbuspacket  = require (name)       break     end     name = "user.luavbuspacket"     local loader = searcher(name)     if type(loader) == 'function' then       package.preload[name] = loader       luavbuspacket  = require (name)       break     end   end

now we go to 

Code:

User library vbus:303: bad argument #3 to 'format' (no value) stack traceback: [C]: in function 'format' User library vbus:303: in function 'packetExtract' User library vbus:205: in function 'waitData'

nobody with a clue?

Most likely that's a "luavbus.log" call. Find the relevant line in the library and add comments before this luavbus.log (--) to disable it:

Code:

-- luavbus.log(...)

But I think that it will fail somewhere else as the original error is caused by a missing variable/value.

I finally got it working thanks to AI. For everybody struggeling. Please find my working script below.

Code:
