Log file filling up with errors that arre't errors

My lsp.log file is filling up with errors like this:

[ERROR][2025-02-05 16:02:17] …/vim/lsp/rpc.lua:770 “rpc” “/home/developer/.local/share/nvim/mason/bin/clangd” “stderr” “I[16:02:17.965] ← textDocument/documentHighlight(1545)\nI[16:02:17.965] → reply:textDocument/documentHighlight(1545) 0 ms\n”

How can I stop these. As far as I can tell this is not an error but an informational message and I have
vim.log_level(“Warn”)
set but these are marked as [ERROR] so they are still getting logged.
There several different msgs but they all come from line 770 of rpc.lua.
