FastAPI FileResponse

[SamuelePignone]

Hi, I'm new to deta and I have a problem. I should download a file, it works locally but when I load the app on deta I get an internal server error but even with visor nothing more comes out to understand the error.

@app.get("/test_download")
async def test_download():
    return FileResponse("file/test.glb")

Thank you in advance !

I guess the source of error is the file path you are using when you are deploying it to deta. You have to use the path from content root.

I thought the same thing but trying to print the os.path.exist result returns me true.

Can you give some more code... like imports and stuff

[SamuelePignone]

Yes, of course
here's all the code

from fastapi import FastAPI
from fastapi.responses import FileResponse

app = FastAPI()

@app.get('/')
async def root():
    return {"message": "Hi"}

@app.get("/test_download")
async def test_download():
    return FileResponse("file/test.glb")

@app.get("/exist")
async def exist():
    return {"msg": os.path.exists("file/test.glb")}

hi

1. disable visor if enabled deta visor disable
2. run a couple requests
3. run deta logs to check for system logs

Ok now I have discovered the error, it is in the decode of the file.

bash UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 8: invalid continuation byte

However, I still don't understand why it works locally and not in deploy

i believe this is a bug in our code. @aavshr, could we look into this?
