[BUG] pyo3_async_runtimes.RustPanic: rust future panicked: unknown error #1059
Description
Describe the bug
Can't get cocoindex running on my M4 mac mini (keyword: Apple Silicone) to work at all:
cocoindex ls failes with an RustPanic
Any ideas?
Here are the minimal steps in an empty directory that reproduces the error on my machine:
❯ uv init
❯ uv add cocoindex

What i tried:
- Tried claude code and gemini to isoloate the bug but got no luck.
- Also tried to compiling cocoindex from source and and linking it to my project. Same result.
- Also tried with different python versions
- cpython-3.11.13-macos-aarch64-none
- cpython-3.12.11-macos-aarch64-none
- cpython-3.13.7-macos-aarch64-none
- cpython-3.14.0rc2-macos-aarch64-none
