[BUG]: invoke `apiNewGroup` and got the error message `Failed reading: empty`

Question

background

I host my own smp-server and I want to develop bot, so I run the simplex-chat CLI and create a node.js project using official package simplex-chat to connect it. The version of all below:

1. smp-server: v6.0.2.0
2. simplex-chat CLI: v6.1.1.0
3. simplex-chat npm package: v0.2.1

re-product

I used this command to run simplex-chat CLI: simplex-chat --database=test --device-name=mbp --server=smp://xxxxxxx@x.x.x.x:6775 --xftp-server=xftp://xxxxxxxx@x.x.x.x:6776 -l debug --display-name=Test -p 8080

and then create the group in my node.js project

    const newGroup = await chat.apiNewGroup({
      displayName: groupName,
      fullName: groupName,
      // image: icon
    })

then I got the error message Failed reading: empty.

Here is the CLI message:

[INFO 2024-11-02 11:04:26 +0800 src/Simplex/Messaging/Transport/Server.hs:188] binding to 127.0.0.1:8080

received command "4" : "/_group {\"displayName\":\"Notification-Center-X\",\"fullName\":\"Notification-Center-X\"}"

I used simplex-chat CLI terminal mode to create group and it didn't have any problem.

Thank you for any help.

Start with the npm package entry point apiNewGroup and compare its request with the CLI's _group command, using the reproduced versions and debug log in the issue. Reproduce the empty-reading error against the stated simplex-chat CLI setup, then confirm that creating the same group through the Node.js package completes without the error.
