Prettier formatter not finding project local .prettierrc configuration file

Bug Report
1

In my project root, I have an .prettierrc.json file dictating formatting. I have a setup imported from vscode, working there but causes an error message in Cursor.

In cursor I get this error message:

["INFO" - 11:04:19] Formatting file:///Users/qludelw/dev/aws/.vscode/settings.json
["ERROR" - 11:04:19] Invalid prettier configuration file detected.
["ERROR" - 11:04:19] ENOENT: no such file or directory, open '/.prettierrc.json'
Error: ENOENT: no such file or directory, open '/.prettierrc.json'
["ERROR" - 11:04:19] Invalid prettier configuration file detected. See log for details.

Seams to be a / too much in /.prettierrc.json, right? A bug? I’m using Cursor Version: 0.42.5 (on VSCode Version: 1.93.1) on OSX Sonoma 14.6.1 on M1,

In vscode (Version: 1.95.3), the same command from the same folder works (and has been working for years) gives this (reduced) output instead:
