Can someone help me make these two mods run in 0.17?

[MrFactorio]

Hello,

I would like to have two mods in 0.17 from 0.16, but they produce errors after start. Just adjusting the .jar file does not help. Something with the code must be wrong and needs fixing

vtk-cannon mod:
https://mods.factorio.com/mod/vtk-cannon-turret

error: ...technology-cannon-turret.kua:74 attempt to index field 'cannon-shell-damage-1' (a nil value)

hovercraft mod:
https://mods.factorio.com/mod/Hovercraft

error: ... data-final-fixes.lua:6: attempt to index field 'flying' (a nil value)

Could someone help me out here? Thank you very much!

How about asking the creators of the mods first?
They may have an update in the pipeline.

I cant contact them because somehow I can not log in to the mod portal... It should be the same as I am using here, but I cant enter

That is the key to your issue - mod portal login is shared with factorio.com login but not forums.

I have updated the mod myself to support 0.17. I have also added a little extra to the mod.
I am more than happy to remove my version of the mod if/when MostlyNumbers returns.
