I use pylsp to do an online IDE, and I wana realize go to definition fuction.

I send to pylsp the definition message like:
b'Content-Length: 202\r\n\r\n{"jsonrpc": "2.0", "method": "textDocument/definition", "params": {"textDocument": {"uri": "file:///home/dev/server/udc_tools_flask/public_project/wsj11.py", "position": {"line": 23, "character": 13}}}}'

the server report error like:
