            You're using --file backend/copium_api/Dockerfile but all build context is relative to . meaning your files are not copied as you expect.
            You have 3 options:

            1. cd into the directory before building (and change COPY backend/copium_api/requirements.txt . to COPY requirements.txt .)
            2. Change your second COPY statement to COPY backend/copium_api/* .
            3. Change your entrypoint to python -m backend/copium_api/server

            You would need to use a Javascript interface/library, such as Fetch API, to make an asynchronous HTTP request. Also, you should use Templates to render and return a TemplateResponse, instead of FileResponse, as shown in your code. Example below:

            The problem is coming from your client code. As you defined your state, initially file is undefined. And since fetching data is asynchronous, sometimes the render happens before you get the data. One way to solve this issue is to initiate your state like this:

            Answered 2022-Feb-24 at 10:19

            When a server side error occurs (a response code of 5xx), the CORS middleware doesn't get to add their headers since the request is effectively terminated, making it impossible for the browser to read the response.

            For your second problem, you should use a separate session for each invocation of your API. The reference guide has an example of how to do this:

            OK I figured it out and now I feel dumb.

            The issue was indeed related to the venv, basically, uvicorn is installed on the base image but not in my pyproject.toml. So poetry didn't install it in the venv. When I started the app in the Dockerfile using CMD it couldn't find uvicorn in the venv so went to the base install and ran from there. When I added uvicorn to the venv it all worked fine.
