Hello all,

 

Im trying to port a simple mod which worked under 1.13.

Minecraft bombs out at the title screen ("Rendering Screen") with a null pointer exception

 

I read a couple threads with similar symptoms where the issue was the mods.toml file having the wrong version numbers, but I updated mine

 

The latest.log file did not show anything, so I have resorted to posting the console output below,  The top of it rolled out of the buffer, but crash is clearly visible

 

My repository is here

 

Thanks as always

/Philip

In general it’s a good idea to search on the forums for similar issues before making your own.

Make sure that you’ve updated your mods.toml file contents to use 1.14.2 instead of 1.13.2 for the Mc version and 26 instead of 25 for the Forge version.

I already updated mods.toml

My bad. However, the only thing that can cause this error AFAIK is not updating your mods.toml.

I've been through it several times now, and checked the copy in the build folder to to be sure.  I'm going to start disabling parts of my mod and see if that makes a difference.

This is where the application is crashing.  I put a breakpoint at this location in the code [return mods.size();]  and the debugger is telling me that 'mods' is null

This would seem to imply that Forge hasn't find the mod, but I'm not sure where to go back to next.

 

I should note this was running correctly under 1.13.2, so I thinks the structure of the mod is generally sound.  I needed to rename some imports and classes, and the rendering classes needed type invocations.

Place a breakpoint right before

And look at the actual error that is thrown. This error is meant to be displayed in a GUI, but MC crashes before it can be displayed

Also, none of this https://github.com/pchonacky/bleeding-edge/blob/50667399b20ad5fd56770297e8d0e64ce0a3eed2/src/main/java/net/chonacky/minecraft/mod/chicken_mod/ChickenMod.java#L40-L42 should be in your code as it is in your mods.toml

Here's what I found:

It's somewhat generic and does seem to say what the issue is.

The only other information seems to be from 2 lines above the EventBus.shutdown.

I also checked the debug.log and didn't find anything useful there :(

By any chance are you using Eclipse and following the instructions in the documentation?

Those instructions are out of date and now actually break your run configs, if this is the case you should disregard the step of modifying the run configuration manually.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Same problem here. Cant run both server and client even with a simple mod template - throwing NullPointerExcetion on title screen on client and net.minecraftforge.fml.LoadingFailedException: null on server.
I make sure I updated mods.toml.

I saw that the run configuration was correct and did not modify.
