You need to include the full file name in the command.

I tried writing out the whole file name and it said the same thing

You did not, as shown by the log.

i just tried it a minute ago

Then send a log of when it doesn't work when you do include the full file name, as in the log you sent you did not include the full file name.

its updated

I was reporting this yesterday and i got answer "use full file name". There is proof, that even with .schematic it doesnt work. https://imgur.com/a/SGCawhV

There is error log (Minecraft 1.13.2)

maybe the schematic used numeric ids and the game (1.13+) didn't understand it.

I hope they will fix it, i really need schematica for > 1.12.2

Schematica works for above 1.12.2. This error is from your schematic being created in the wrong version.
