Error message

This operation is not supported, please go to the cloud storage provider management console to operate

What it means

CreateCloudSyncDir only allows the SiYuan and Local providers through its switch; every other provider (S3, WebDAV) gets i18n key 131 ('This operation is not supported, please go to the cloud storage provider management console to operate'). SiYuan cannot create buckets or directories on external storage services through its API, so nothing is created.

Solutions

1. Create the bucket or directory in the provider's own management console, then select it as the sync dir
2. Or switch the provider back to SiYuan or Local if in-app directory creation is required

func canManageCloudSyncDirs(provider int) bool {
	return provider == conf.ProviderSiYuan || provider == conf.ProviderLocal
}

if !canManageCloudSyncDirs(model.Conf.Sync.Provider) {
	// create the bucket/dir in the provider console instead of calling the API
	return nil
}
model.CreateCloudSyncDir(name)

func canManageCloudSyncDirs(provider int) bool {
	return provider == conf.ProviderSiYuan || provider == conf.ProviderLocal
}

When it happens

Trigger: Calling CreateCloudSyncDir (POST /api/sync/createCloudSyncDir, Settings - Sync - add cloud sync directory) while Conf.Sync.Provider is S3 or WebDAV.

Common situations: After switching the provider to S3/WebDAV, a stale UI tab or automation script still calls the create-directory endpoint.
