📄 Description

Updated the uvicorn startup command to dynamically detect and use either 'python3' or 'python', ensuring compatibility across different environments and pyenv setups. This avoids issues where only one of the commands is available.

Description

Updated the uvicorn startup command to dynamically select the appropriate Python interpreter (python3 or python) based on availability. This improves environment compatibility, especially in systems using pyenv or where only one of the commands is present.

Added

Dynamic detection of the Python interpreter using command -v python3 || command -v python.

Changed

Modified uvicorn execution to be launched via the detected Python interpreter instead of relying on a system-wide uvicorn binary.

Deprecated

N/A

Removed

N/A

Fixed

Addressed compatibility issues in environments where uvicorn is not installed globally but is available as a Python module.

Security

N/A

Breaking Changes

None

Additional Information

This change improves cross-environment consistency and avoids startup failures due to missing or misconfigured uvicorn executables in virtual environments or custom Python installations.
