[Python] Uvicorn reload_excludes not working for one directory but working for another...

I'm running a FastAPI application with uvicorn and using reload_excludes to prevent the server from reloading when files are added to certain directories. The issue is that the exclusion works for one directory (generated_scripts) but completely fails for another directory (generated_tools) that has the exact same structure and configuration.

Directory Structure


src/
└── ai_processing/
├── main.py
├── generated_scripts/ # Exclusion works - no reload when files added
└── generated_tools/ # Exclusion fails - server reloads when files added


Both directories:

• Exist at the same level
• Are created with the same permissions
• Have identical structure
• Are specified with identical patterns in reload_excludes

Current Code


if __name__ == "__main__":
uvicorn.run(
"main:app",
host="127.0.0.1",
port=8000,
reload=True,
reload_excludes=[
"src/ai_processing/generated_scripts/*",
"src/ai_processing/generated_tools/*"
]
)

1. Tried all of these patterns:

reload_excludes=[
"src/ai_processing/generated_scripts/*",
"src/ai_processing/generated_tools/*",
"src/ai_processing/generated_scripts/**",
"src/ai_processing/generated_tools/**",
"**/generated_scripts/**",
"**/generated_tools/**",
"src\\ai_processing\\generated_tools\\*", # Windows path separator
]

1. 
   Verified directory existence and structure
   
   
2. 
   Tried creating directories if they don't exist
   

pythonPath("src/ai_processing/generated_scripts").mkdir(parents=True, exist_ok=True)
Path("src/ai_processing/generated_tools").mkdir(parents=True, exist_ok=True)

1. Tried using reload_dirs in combination

uvicorn.run(
"main:app",
reload=True,
reload_dirs=["src"],
reload_excludes=[
"src/ai_processing/generated_scripts/*",
"src/ai_processing/generated_tools/*"
]
)
