[jsonRpc] Command returns a NullPointerException (Solved: Missing "recipient" param)

[LunarN0v4]

When running:

printf '{"jsonrpc":"2.0","method":"sendReceipt","id":1,"params":{"targetTimestamp":1728134498289}}' | socat UNIX-CONNECT:/run/user/1000/signal-cli/socket -

I get this as a response:

{"jsonrpc":"2.0","error":{"code":-32603,"message":"Cannot invoke \"String.startsWith(String)\" because \"identifier\" is null (NullPointerException)","data":null},"id":1}

Signal-CLI version: 0.13.7
Running on: Arch Linux (Linux 6.11.1-arch1-1)

You're missing the recipient field in the params: "recipient":"+1234567890"

That seems to have fixed the problem, thank you!
