Save handler can't find package

[tbo]

I've encountered an issue in my development setup involving Prettier, the prettier-plugin-tailwindcss plugin, and a PNPM monorepo environment. Notably, when I save a file, the expected formatting by Prettier doesn't take place. While there's no immediate error message displayed on save, I unearthed an error in the logs when inspecting with :CocOpenLog.

Running the Prettier CLI directly via the command ./node_modules/.bin/prettier ./src/ --write executes without any hitches, ensuring proper formatting. However, the in-editor save functionality seems to be at odds. A temporary relief can be achieved by restarting CoC using the :CocRestart command. After that, everything works as expected.

This behavior began roughly two weeks ago. I'm inclined to consider that it could be intertwined with recent modifications, potentially those related to the Prettier 3.0 upgrade.

This is happening for me as well. In my case I am also using Prettier 3 and have the following .prettierrc.yml file:

# All of these are defaults except singleQuote and endOfLine, but we specify them
# for explicitness
endOfLine: auto
singleQuote: true
trailingComma: all
plugins: ['prettier-plugin-sort-json']

I am getting a similar error: Error resolve node module 'prettier-plugin-sort-json'.
