ERROR tower_lsp::transport: failed to decode message

[nkabbara]

Hello,

I installed the extension and diagnostics work, but when I hover over any of them I'm seeing the following in the logs

2025-03-27T01:37:46.997291-03:00 [WARN] Get code actions via harper-ls failed: server shut down
2025-03-27T01:37:46.997868-03:00 [ERROR] Get code actions via harper-ls failed: server shut down

I started the server on the command line to see what's happening and I found the following err out:

2025-03-27T04:37:49.613628Z ERROR tower_lsp::transport: failed to decode message: missing required `Content-Length` header
Content-Length: 75

{"jsonrpc":"2.0","error":{"code":-32700,"message":"Parse error"},"id":null}

Ideas on how I can debug this?

Thank you.

Mac/M2

As far as I know the error you got when manually starting the server is not that useful because it needs certain JSON input from the editor.

As for 2025-03-27T01:37:46.997868-03:00 [ERROR] Get code actions via harper-ls failed: server shut down, this is indeed not that useful. I'm not entirely sure where to go from there, I haven't used Zed or have had access to a Macbook in months, sorry about that.
