juicefs format --bucket parameter for Hetzner (S3) Object Storage

[nedix]

I've tried all sorts of combinations for the --bucket parameter. For example have a look at this format command:

juicefs format \
    --access-key="$S3_ACCESS_KEY_ID" \
    --bucket="https://${S3_BUCKET}.${S3_ENDPOINT}" \
    --secret-key="$S3_SECRET_ACCESS_KEY" \
    --storage="s3" \
    sqlite3://myjfs.db \
    "$S3_BUCKET"

This results in the following juicefs logging: juicefs[119] <INFO>: Data use s3://fsn1.your-objectstorage.com/<BUCKET_NAME>/<BUCKET_NAME>/ [format@format.go:527]. So the bucket name is repeated.

Also tried options such as:
--bucket="s3.${S3_REGION}.${S3_ENDPOINT}"

OR

--bucket="s3.${S3_ENDPOINT}"

OR

--bucket="$S3_ENDPOINT"

.

Hetzner console says that fsn1.your-objectstorage.com should be the endpoint URL and region should be eu-central. I even found documentation at Hetzner that reads that it should be compatible, link here (How do I mount a Bucket in a local filesystem?)

In the JuiceFS documentation I found some information about hosted-style and path-style endpoints, which I used to try different --bucket options to no avail.

The last parameter of the "juicefs format" command is the "volume name". It seems that this issue occurs because the bucket name and volume name you are using are the same. Try using different names instead?
