Timeout in neovim LSP

[jheuel]

Problem description

Trying to format the current neovim buffer using vim.lsp.buf.format fails with a message that the LSP times out. It runs instantly if I only use rustfmt without leptosfmt. Increasing the timeout to 5s still fails, while running leptosfmt . on the whole project in the terminal finishes in well under a second. My system is a M1 MacBook Pro.

Configuration

Leptosfmt is configured in the recommended way by creating a rust-analyzer.toml with the content

[rustfmt] 
overrideCommand = ["leptosfmt", "--stdin", "--rustfmt"]
