Null response without an error

[GoldenGamerLP]

Describe the bug
So when you trying to load up a schematic via Scaffolding.fromFile or via the FileInputStream the response is always null. There is no exception too which would be thrown. BTW my entire completeable future is beeing closed but i have no idea what why and whats caused it...

To Reproduce
Steps to reproduce the behavior:

1. Load up a schematic
2. look via if(schematic != null) if its null
3. Use it in a CompleteableFuture
4. See null response with no error (Schematics are tested and worked fine)

Expected behavior
It should throw an error and should load when the schematics are right, load them up.

(- Please ask for a full code snippet)

Desktop (please complete the following information):

What kind of schematic are you using? MCEdit or Sponge?

[GoldenGamerLP]

I tried both types and also renamed them both to .schematic

[LooFifteen]

Are you able to send a screenshot of the schematic open in NBTExplorer?

[GoldenGamerLP]

1. Schematic:
   
2. Schematic:
   

• Not NBT explorer sorry, i cant install it rn

Schematic 1 is a Sponge schematic, try loading it using new SpongeSchematic()#read. I don't recognise the second one, are you able to send the file for me to check out tomorrow?

[GoldenGamerLP]

Yes the first one is Sponge, the second one had a .nbt thing at the end. Ill try the new SpongeSchematic()#read later. Thanks

So i created the Schematic by myself but it didnt work either

[LooFifteen]

How exactly did you know it didn't work?

[GoldenGamerLP]

How exactly did you know it didn't work?

When I read the nbt via fileinputstream, it caused my whole completable future to exit und stop working, even my debug messages after the loop wouldn't print out.

[LooFifteen]

I will need the schematics to reproduce this.

[GoldenGamerLP]

Yes, i downloaded a random schematic, here it is: https://workupload.com/file/RNfUqkkMXZc

[GoldenGamerLP]

So i tried reading the NBT data myself and this error occoured with this code:
Error:

Code to reproduce:

[LooFifteen]

Okay, I'll look into this sometime tomorrow.

[GoldenGamerLP]

Thanks ^^

The schematic you provided has loaded on my machine, but the block palette is slightly off.

[GoldenGamerLP]

Ah okay, I have no more ideas why it isn't loading and exiting my whole completable furutre. Do you maybe have an idea where the error which I send you is coming from?

[LooFifteen]

It may be caused by the fact you are not on the 1.18 branch of Minestom.

[GoldenGamerLP]

That could be true, I'm using the latest version of the main branch (-SNAPSHOT)

[GoldenGamerLP]

Any news on the bug?

[LooFifteen]

I'm not sure, I was able to read and build the schematic perfectly fine. I did discover a different bug but it was unrelated to your issue.
