Better MC Modpack | Fabric | 1.19.2

Hi, I had the same problem.

I let a server hosting automatically install the Fabric Better MC Modpack on my server.
But the server.jar wasn't Fabric but Forge.

I got the same error: Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(12) + length(1) exceeds writerIndex(12): PooledUnsafeDirectByteBuf(ridx:12, widx: 12, cap:12/13)

How can fixed?
