What causes "Conf.Language(30) {err.Error()}" in siyuan-note/siyuan?

Verify network connectivity to the cloud provider endpoint

Conf.Language(30) {err.Error()}

Error message

Conf.Language(30) {err.Error()}

What it means

The GetCloudSpace function queries the cloud provider for sync, backup, and asset storage usage statistics. When the underlying getCloudSpace call fails (network error, auth failure, or API error), the function wraps the error with Language(30) as a prefix and returns it. The error message combines a localized error label with the raw underlying error detail.

Solutions

Verify network connectivity to the cloud provider endpoint
Re-login to the SiYuan cloud account in Settings - Account if the token has expired
Check the kernel log for the detailed err.Error() component to identify the specific cloud API failure
If using WebDAV/S3, verify the server URL, credentials, and that the endpoint is responding

Defensive patterns

Strategy: try-catch

Validate before calling

// Pre-check cloud connectivity before calling GetCloudSpace
if model.Conf.Sync.Provider == 0 {
    // no provider configured, skip space query
    return
}

Try / catch

// Handle cloud space query failure gracefully
stat, err := model.GetCloudSpace()
if err != nil {
    // show placeholder values instead of crashing the settings panel
    hSize = "-"
    hTotalSize = "-"
    logging.LogErrorf("get cloud space failed: %s", err)
}

Prevention

Cache the last successful cloud space result and display it when the API fails
Add a timeout to the cloud space query to prevent the settings panel from hanging
Show placeholder dash values in the UI when the query fails rather than an error screen
Verify authentication status before querying cloud space

When it happens

Trigger: Calling GetCloudSpace (typically from the Settings - Account & sync space usage display) when the cloud API is unreachable, returns an error, or the authentication token has expired. The function delegates to getCloudSpace which makes the actual HTTP request to the cloud provider.

Common situations: Network connectivity issues to the SiYuan cloud or third-party provider (WebDAV/S3). Expired login sessions where the auth token is no longer valid. Cloud provider maintenance or downtime. Also seen when the user has not logged in but the settings panel tries to load space statistics.
