Is "import on demand" supported for S3 Gateway?

[adamwaabi]

Hello,

Is the import on demand feature supported for JuiceFS S3 Gateway? According to the command reference, the juicefs gateway command shares options with the juicefs mount command: https://juicefs.com/docs/cloud/reference/command_reference#options-11. However, when I try passing --source=/ to juicefs gateway to enable import on demand as the docs specify for juicefs mount, I get this error:
gateway 2025/10/24 15:43:14.555826 juicefs[7] <FATAL>: unknown option: --source=/ for command gateway [[email protected]:291]

Any insight would be appreciated. Thanks!

JuiceFS S3 Gateway does not support the --source option or import on demand functionality.
