7Zip CLI Compress file with LZMA - compression

Question

I try to compress a file in the console with LZMA.
7z a -t7z output input
or
7z a -t7z -m0=lzma output input
However, I cannot open it on the client.
How can compress a file as an LZMA archive in the console?
It is possible the problem to be that the above commands add a file in an archive. However, I want to compress data in a data file without file structure.
Is there an option to compress a data file to a compressed data file with LZMA?
Edit
I see downvotes, which means the question is "not correct" in some way.
So I'll try to explain what I want to achieve.
I compress data serverside and use them on a client application. I successfully do it in Node.js like that:
const lzma = require('lzma');
lzma.compress(inputBuffer, 1, callback);
function callback(data, err) {
writefile(outputPath, Buffer.from(data));
}
However, it is very slow. So I want to call 7Zip for the compression.
My .NET server also compresses it in a similar way.
byte[] barData;
using (var barStream = dukasDataHelper.SerializeLightBars(lightBars.ToArray()))
using (var zippedStream = zipLzma.Zip(barStream))
{
barData = zippedStream.ToArray();
}
My problem is that I cannot set the correct options in CLI in order to be able to read the file in the client.
My client code C# is:
using (var blobStream = new MemoryStream(blobBytes))
using (var barStream = new ZipLzma().Unzip(blobStream))
{
SaveDataSet(barStream, localPath);
}
I have this error message when compress via CLI:
$exception {"Data Error"}
Data: {System.Collections.ListDictionaryInternal}
at SevenZipLzma.LZMA.Decoder.Code(Stream inStream, Stream outStream, Int64
inSize, Int64 outSize, ICodeProgress progress)
at SevenZipLzma.ZipLzma.Unzip(Stream stream)
Since the code works as I compress with Node.js and doesn't work when compressing via CLI, it means something is wrong.

7zip makes an archive of files and directories, whereas LZMA generates a single stream of compressed data. They are not the same format. LZMA can be used inside a 7zip archive to compress an entry (or LZMA2 or Deflate or several other compression methods).
You can try the xz command to generate LZMA streams with xz --format=lzma.
