Image attachment doesn't work

[unoexperto]

Guys, could you please provide example of working settings for AWS ? I cannot understand what I'm doing wrong :( Mine are

docker run -d --name=outline --restart always \
    --network isolated \
    -e NODE_ENV=production \
    -e DEPLOYMENT=self \
    -e DEBUG=cache,presenters,events \
    -e SECRET_KEY=xxx \
    -e URL=https://xxx.zzz.com \
    -e PORT=8081 \
    -e DATABASE_URL=postgres://uuu:ppp@psql:5432/outlinedb \
    -e PGSSLMODE=disable \
    -e REDIS_URL=redis://redis:6379 \
    -e SLACK_KEY=ddd \
    -e SLACK_SECRET=vvvv \
    -e GOOGLE_CLIENT_ID=vvvv \
    -e GOOGLE_CLIENT_SECRET=xxxx \
    -e AWS_ACCESS_KEY_ID=www \
    -e AWS_SECRET_ACCESS_KEY=ffff \
    -e AWS_REGION=us-east-1 \
    -e AWS_S3_UPLOAD_BUCKET_URL=https://s3.amazonaws.com \
    -e AWS_S3_UPLOAD_BUCKET_NAME=xxxzzz \
    -e AWS_S3_ACL=public-read \
    -e AWS_S3_UPLOAD_MAX_SIZE=26214400 \
    -e AWS_S3_FORCE_PATH_STYLE=false \
    -e FORCE_HTTPS=false \
    -e SMTP_HOST=smtp-relay.gmail.com \
    -e SMTP_PORT=25 \
    -e SMTP_FROM_EMAIL=noreply@zzz.com \
    outlinewiki/outline:latest

This almost works. I see POST request to https://s3.amazonaws.com/walkmindoutline with image. AWS responds with 204 No Content and link to uploaded file in Location header. But apparently it's never used so image doesn't appear in the document. Link that I see in log is https://s3.amazonaws.com/walkmindoutlineus/uploads%2Fcbdecf64-69c4-449f-a8bb-1d7c286ad49c%2F235a56a4-889b-45c9-a554-14ea246208a1%2Fimage.png

Interestingly if I change AWS_S3_UPLOAD_BUCKET_URL to s3.amazonaws.com Outline acts as if it uploaded the image and even displays placeholder for it in the document. But it's not pushed to the bucket.

Could you please advise what I'm missing ?

I tried suggestions from #1092

Try removing AWS_S3_FORCE_PATH_STYLE=false, seems like you're disabling it – but with that generic bucket url you'd need to use the path-style routing.

Thanks for posting all the details about the setup, very helpful.
