Would like to test some jsonrpc on pylsp. There for I want to use bash. I opened terminal and execute the send function. But pylsp throws an error. Why pylsp has problem to parse JSON message?

$ send() { msg=$(jq -n "$@"); printf "%s\r\n" "Content-Length: ${#msg}" "" "$msg"; }

$ send '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"processId": null, "rootPath": null, "rootUri": "file:///home/user", "capabilities": {}, "workspaceFolders": null}}' | pylsp

But it throws errors I couldn't resolved:

Content-Length: 777
