Error importing to ActualServer (Docker)

[d-mcknight]

I am running the Docker container as described in the readme and receive the following error:

open file
connect
/app/node_modules/@actual-app/api/dist/app/bundle.api.js:34731
                        throw new Error('Could not get remote files');
                              ^

Error: Could not get remote files
    at handlers.api/download-budget (/app/node_modules/@actual-app/api/dist/app/bundle.api.js:34731:31)

Node.js v21.7.1

I do see a list of my accounts and budgets printed before that error. I ran the container with:

docker run -e ACTUAL_SERVER_PASSWORD="<my password>" -e ACTUAL_SYNC_ID="<my sync id>" -e ACTUAL_SERVER_URL="http://192.168.1.100:5006" -v ./Downloads/transactions.csv:/data/transactions.csv actual_mint_importer:latest

I also tried with -e NODE_TLS_REJECT_UNAUTHORIZED=0 and using an https URL (nginx + letsencrypt cert) instead of the IP/Port.
