Error when uploading to WorldEdit

[Janaane]

I converted from .nbt to .schem

but when I execute a command on my server //schematic load image1

then I get this error [ERROR]: Uncaught exception occurred in task: Loading schematic image1 java.io.IOException: Schematic file is missing a "Version" tag of type com.sk89q.jnbt.IntTag at com.sk89q.worldedit.extent.clipboard.io.NBTSchematicReader.requireTag(NBTSchematicReader.java:36) ~[?:?] at com.sk89q.worldedit.extent.clipboard.io.SpongeSchematicReader.getBaseTag(SpongeSchematicReader.java:157) ~[?:?] at com.sk89q.worldedit.extent.clipboard.io.SpongeSchematicReader.read(SpongeSchematicReader.java:91) ~[?:?] at com.sk89q.worldedit.command.SchematicCommands$SchematicLoadTask.call(SchematicCommands.java:322) ~[?:?] at com.sk89q.worldedit.command.SchematicCommands$SchematicLoadTask.call(SchematicCommands.java:304) ~[?:?] at com.sk89q.worldedit.command.util.AsyncCommandBuilder.runTask(AsyncCommandBuilder.java:158) ~[?:?] at com.google.common.util.concurrent.TrustedListenableFutureTask$TrustedFutureInterruptibleTask.runInterruptibly(TrustedListenableFutureTask.java:111) ~[patched_1.16.5.jar:git-Paper-794] at com.google.common.util.concurrent.InterruptibleTask.run(InterruptibleTask.java:58) ~[patched_1.16.5.jar:git-Paper-794] at com.google.common.util.concurrent.TrustedListenableFutureTask.run(TrustedListenableFutureTask.java:75) ~[patched_1.16.5.jar:git-Paper-794] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[?:1.8.0_462] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[?:1.8.0_462] at java.lang.Thread.run(Thread.java:750)[?:1.8.0_462]
